Answer:
x = -3/2 x=1
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
