Question

What is the factored form of the expression?

Answer 1

\[3x ^{2} + 8x – 16\]

Answer 2

A. (3x + 4)(x – 4)
B. (3x + 4)(x + 4)
C. (3x – 4)(x – 4)
D. (3x – 4)(x + 4)

Answer 3

\[3x^2+ 12x - 4x - 16\]

\[3x \left( x+4 \right) - 4\]

\[\left( 3x+4 \right)\]

Answer 4

Well, 3x^2 + 8x - 16
1 * 16, 2 * 8, 4 * 4, all go into 16,
And only 1 * 3 go into 3,
So, what works? (3x - 4)(x + 4 )

Answer 5

Thanks, @Kyle15

Answer 6

3x(x+4)-4(x+4)
