2x^2+x-1=2, What would the solutions be? I've been trying to solve this for a little now and I can't seem to find the answers.

x = - 3/2 x=1

Step-by-step explanation:

2x^2+x-1=2

Subtract 2 from each side

2x^2+x-1-2=2-2

2x^2+x-3=0

Factor

(2x) (x)

We will use - 3 and 1 or - 1 and 3 because we need - 3 as the last term

2*1 - 3 = -1 wrong we need 1

2 * - 1 + 3 = 1 correct this will give us 1 as the middle term

The - 1 goes on the outside and the + 3 goes on the inside

(2x + 3) (x - 1) = 0

Using the zero product property

2x+3 = 0 x-1=0

2x = - 3 x=1

x = - 3/2 x=1
