Question

Factor completely: 2x^2 − 4x − 48

(2x − 12)(x + 4)

2(x − 6)(x + 4)

(x − 6)(2x + 8)

Prime

Answer 1

GCF is 2
so.
2(x^2-2x-24)

Answer 2

Now find a number when adding or subracting is 2 and multiplying is 24 so, -6 +4=-2
and 6 x 4=24

x^2-2x-24
x^2-6x+4x-24
x(x-6)+4(x-6)
So,
2(x-6)(x+4) ans.
