Question

2x^-8x^-4=0


^=square ​

Answer 1

Answer:

2x2 - 8x - 4 = 2 • (x2 - 4x - 2)

Trying to factor by splitting the middle term

3.2 Factoring x2 - 4x - 2

The first term is, x2 its coefficient is 1 .

The middle term is, -4x its coefficient is -4 .

The last term, "the constant", is -2

Step-1 : Multiply the coefficient of the first term by the constant 1 • -2 = -2

Step-2 : Find two factors of -2 whose sum equals the coefficient of the middle term, which is -4 .

-2 + 1 = -1

-1 + 2 = 1
