Question

Factor completely. f(x) = −16x2 + 22x + 3

Answer 1

8x(2x+3)-2(x+3)

step by-step explanation:

16x^2+22x+3

16*3=48

2 numbers which have a product of 48 and a sum of 22

=24 and -2

Rewrite the centre term as these two numbers, so

16x^2+24x-2x+3

Factorise each pair of terms.

8x(2x+3)-2(x+3)
