Factoring x^2 + bx + c Factoring x 2 + b x + c In the last few lessons, you learned how to expand expressions like ( x + 2) ( x + 3) into x 2 + 5 x + 6. In this lesson, you’ll learn how to reverse this process, starting with a polynomial like x 2 + 5 x + 6 and writing it as a product like ( x + 2) ( x + 3).

Example 3A: Factoring x2 + bx + c When c is Negative. Factor each trinomial. x. 2 + x – 20 (x + )(x + ) b = 1 and c = –20; look for factors of –20 whose sum is 1. The factor with the greater absolute value is positive. The factors needed are +5 and –4. Factors of …

For ax2+bx+c, one can use that the roots are −b±√b2−4ac2a. Here, that means the roots are −1±√ ...

15.2 Factoring Trinomials of the Form x2 + bx + c.

In order to factor x 2 + b x + c, you need to find two numbers whose product is c and whose sum is b. For example, suppose you wanted to factor x 2 + 4 x + 3. You could notice that the numbers 1 and 3 multiply to make 3 (the constant coefficient) and add up to 4 (the linear coefficient).
