Exercise 75 Page 176

Try to group terms with common factors.

2(2x-3y)(8a+3b)

Practice makes perfect

To factor given polynomial, we will start by grouping terms with common factors. 32a x+12b x-48a y-18b y ⇕ (32ax+12bx)+(- 48ay-18by) Now, we can factor out a greatest common factor - GCF - from each group of terms. Let's do it!

(32ax+12bx)+(- 48ay-18by)

FactorOut

Factor out 4x

4x(8a+3b)-48ay-18by

FactorOut

Factor out - 6y

4x(8a+3b)-6y(8a+3b)

FactorOut

Factor out (8a+3b)

(4x-6y)(8a+3b)
