3.3 Find roots (zeroes) of : F(x) = 4x2 + 1Polynomial Roots Calculator is a set of methods aimed at finding values of x for which F(x)=0 Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers x which can be expressed as the quotient of two integersThe Rational Root Theorem states that if a polynomial zeroes for a rational number P/Q then P is a factor of the Trailing Constant and Q is a factor of the Leading CoefficientIn this case, the Leading Coefficient is 4 and the Trailing Constant is 1. The factor(s) are: of the Leading Coefficient : 1,2 ,4 of the Trailing Constant : 1 Let us test ....

4.1 A product of several terms equals zero. When a product of two or more terms equals zero, then at least one of the terms must be zero. We shall now solve each term = 0 separately In other words, we are going to solve as many equations as there are terms in the product Any solution of term = 0 solves product = 0 as well.

Lines with various slopes are shown in Figure 7.8 below. Slopes of the lines thatgo up to the right are positive (Figure 7.8a) and the slopes of lines that go downto the right are negative (Figure 7.8b). And note (Figure 7.8c) that because allpoints on a horizontal line have the same y value, y2 - y1 equals zero for any twopoints and the slope of the line is simply

This approach to solving equations is based on the fact that if the product of two quantities is zero, thenat least one of the quantities must be zero. In other words, if a*b = 0, then either a = 0, or b = 0, or both.For more on factoring polynomials, see the review section P.3 (p.26) of the text.

The calculator will find all possible rational roots of the polynomial using the rational zeros theorem. After this, it will decide which possible roots are actually the roots. This is a more general case of the integer (integral) root theorem (when the leading coefficient is $$$1$$$ or $$$-1$$$). Steps are available.

The rational root theorem, as its name suggests, is used to find the rational solutions of a polynomial equation (or zeros or roots of a polynomial function). The solutions derived at the end of any polynomial equation are known as roots or zeros of polynomials. A polynomial doesn't need to have rational zeros. But if it has rational roots, then they can be found by using the rational root theorem.

The rational zero theorem is used to find the list of all possible rational zeros of a polynomial f(x). Here, the word "possible" means that all the rational zeros provided by the rational root theorem need NOT be the actual zeros of the polynomial. Here are the steps to find the list of possible rational zeros (or) roots of a polynomial function. The steps are explained through an example where we are going to find the list of all possible zeros of a polynomial function f(x) = 2x4 - 5x3 - 4x2 + 15 x - 6.

In the previous section, we have seen how to find the list of possible zeros of a polynomial function. But all the numbers from the list may not be the actual zeros. We can find the actual rational zeros by using the remainder theorem (i.e., by substituting each zero in the given polynomial and see whether f(x) = 0). Once we find the rational zeros, sometimes it is possible to find the other roots (irrational roots or complex roots) as well. Here are the steps for the same. In these steps, we will find all the zeros of the same polynomial (as in the previous section) f(x) = 2x4 - 5x3 - 4x2 + 15 x - 6.

The constant term is 2 and its factors are 1 and 2. These would be the values of p.The leading coefficient is 3 and its factors are 1 and 3. These would be the values of q.Then by the rational zero theorem, the possible rational roots of f(x) are all possible values of p/q.

From Example 2, we found that the rational zero of f(x) is -1/3.Let us divide the given polynomial by x = -1/3 (or we can say that we have to divide by 3x + 1) using synthetic division.

In the rational zero theorem, p and q stand for all potential rational roots of a polynomial. p represents all positive and negative factors of the constant of the polynomial whereas q represents all positive and negative factors of the leading coefficient of the polynomial.

For finding the rational zeros of a polynomial function, just find all possible values of p/q where p is a factor of the constant of polynomial and q is a factor of the leading coefficient of the polynomial. Then we get a set of numbers. Substitute each number in the polynomial (or divide the polynomial by each number by synthetic division) and see which one would result in 0.
