Question

How do you use the quadratic formula to solve `2x^2+2x=4x-1`?

Answer 1

Find Delta first and then compute results.

Explanation:

Yur equation is
`2x^2-2x+1=0`

when you arrange your original equation. Now you can compute Delta:

`Delta=b^2-4ac` (where b=-2, a=2 and c=1].

`Delta=4-8=-4`

If Delta is negative there is no solution (in real numbers)
