Question

Factor each of the ff. completely

1. 3x^2-12
2. 3x^2+17x-16

Answer 1

For #1

Pull out a 3 and obtain:
\[3(x ^{2}-4)\]

If you notice it's much easier now and a difference of squares with a constant multiple of 3:

3(x-2)(x+2)

Answer 2

Can you please stop tagging every person you know in every question...
Post it so everyone can see it, and learn from it

Answer 3

Agreed that is annoying.
