Math 0302, Practice Test 5: Factoring and Solving Polynomial Equations by Factoring Instructions: Factor the greatest common factor from the following polynomial. #1 9y2 −15y3 + 33y4 Instructions: Factor each of the following polynomials completely #2 x2 + 6x + 5 #3 x2 − 2x −15...
Factoring is a very powerful tool for finding roots of polynomial equations. Some polynomial equations of a degree higher than two can be factored by grouping or by ordinary factoring methods. Example 1: Solve 4 x3 + 3 x2 − 36 x − 27 = 0. Factor by grouping into two sets of bin...
But because the equation was written as the product of two terms, we could use the zero product principle. What if we are given a polynomial equation that is not written as a product of two terms, such as this one2y2+4y=02y2+4y=0? We can use a technique called factoring, where w...
Since one side of the equation is equal to zero, the first step is to factor the polynomial. Next, we use The Multiplication Property of Zero. This means we set the factors equal to zero. Solving each of these linear equations separately, we get… If you would like to view our vi...

Instead of solving x^4 + 2x^3 = 0, factoring the binomial means you solve two simpler equations: x^3 = 0 and x + 2 = 0. A binomial is any polynomial with two terms; the variable can have any whole-number exponent of 1 or higher. Learn which binomial form

Solve a quadratic equation by factoring. A quadratic equation is a polynomial equation that contains the second degree, but no higher degree, of the variable. The standard form of a quadratic equation is ax2+ bx + c = 0 when a ≠ 0 and a, b, and c are real numbers. ...
Factoring can also be applied to polynomials of higher degree, although the process of factoring is often a bit more laborious. Recall that a polynomial of degree n has n zeros, some of which may be the same (degenerate) or which may be complex.
Quadratic formula: For a quadratic equation ax2+bx+c=0, the solutions of the equation can be found by:x=−b±b2−4ac2a Example Problem 1 - Solve Polynomial Inequalities with Linear and Quadratic Factors Solve the inequality: (x−1)(x2−4)(x+3)>0. Step 1: Rewrite ...
