## anonymous 5 years ago Which is a factor of 8x2 – 12x – 8 ? x + 1 x – 4 2x – 2 2x + 1

1. anonymous

(x-2) (2x+1)

2. anonymous

$$8x^2–12x –8 =4(x-2)(2x+1)$$

You can factorize a polynomial by finding its roots. If it has the roots x_i you can write is as $\text{constant}\cdot (x-x_0)\cdot(x-x_1)\cdot\cdots\cdot(x-x_n)$

So the answer from the problem statement is: 2x + 1
