Question

Which expression is equivalent to this polynomial expression? (2a – 36)(2a2 + 662) + (6a26 + 12a62 – 783)​

Answer 1

1. Look for factors that each term has in common.

They all have a "b" so factor that out.

a2b + 2ab - 8b = b(a2 + 2a - 8)

2. Factor the remaining polynomial.

Factors of -8 that add to 2 are 4(-2)

a2 + 2a - 8 = (a+4)(a-2)

Final answer: b(a+4)(a-2)
