The solutions to the equation 2x^2+x-1=2 are x=-3/2 or x= blank

Step-by-step explanation:

hello :

2x²+x-1=2  means : 2x²+x-3=0

a=2  b= 1  c= -3

the solutios are :   x1 and x2 when the product is : x1×x2 = c/a  

let x1 = -3/2  you have : (-3/2)×x2 = -3/2   so x2 = (-3/2)/(-3/2) = 1  

The solutions to the equation 2x²+x-1=2 are x=-3/2 or x= 1
