**AC Method of factoring ax2 + bx +c**

E.Q. How is ax2 + bx +c put into factored form?

2
AC METHOD 3x2 +11x + 10 Looking at your quadratic equation first list a, b and c. a = 3, b = 11, c = 10 2. Multiply a times c. ac = = 30 List all the factors of ac. ac = Add factors to find sum of “b = 11”

3
**Original Equation: 3x2 +11x + 10**

5. Use the factors to rewrite the middle term of the original equation. Original Equation: 3x2 +11x + 10 Rewrite as: 3x2 +5x +6x +10 Factor by grouping. (3x2 +5x) (+6x +10) 7. Find GCF of each group 3x2 +5x = x(3x + 5) and 6x +10 = 2(3x + 5) Notice both groups in parenthesis are the same!!!

4
**(x+2)(3x+5) 8. Rewrite your groups x(3x + 5) and 2(3x + 5)**

to get the final answer. (x+2)(3x+5) 9. Check by FOILing.
