Question

Factor completely 2x2 + 4x − 2.

2(x2 + 2x − 1)
2(x2+ 2)
2x(x2 + 2x − 1)
Prime

Answer 1

2X²+4X-2
=2(X²+2X-1）
So, your answer is choice one: 2(X²+2X-1).

Answer 2

Option A is correct

factor completely of
`2x^2+4x-2` is
`2(x^2+2x-1)`

Explanation:

GCF(Greatest Common Factor) states that the largest factor that divides the polynomial.

Given the expression:

`2x^2+4x-2`

By definition of GCF we have;

Factor a GCF of the given expression.

Since GCF of
`2x^2`, 4x and -2 is 2.

then;

`2(x^2+2x-1)`

Therefore, factor completely
`2x^2+4x-2` is
`2(x^2+2x-1)`
