# 2 examples of quadraric trinomials, and by getting the answer of it you'll use the grouping method. And the variables that will be used are going to create a 4-letter word?

5x²+7x-6

grouping method:

If 5x²=a, 7x=b and -6=c

1. Find the grouping num.of AC

a= 5x² c= -6 ac= -30

2. Find the grouping number whose sum is b

Factors of -30 SUM

30,-1 29

15, -2 13

6, -5 1

10, -3 = 7

3. Use these factors tpwrite bx as the sum of two terms

7x= 10x-3x

4.Factor by grouping

5x²+7x-6

5x²+10x-3x-6

(5x²+10) (-3-6)

5. Get its GCF.

(5x²+10)= 5x

(-3-6)= -3

5x(x+2) -3(x+2)

6.Same terms

x+2

(x+2) (5x-3)
