Question

How do you solve the quadratic equation by completing the square: `(2x-3)^2=8`?

Answer 1

I think you already completed the square (on the left)!!!

Explanation:

You can take the square root of both sides:
`2x-3=+-sqrt(8)`
so you get two solutions; rearranging:
`x_1=(3+sqrt(8))/2`
`x_2=(3-sqrt(8))/2`
