i am doing completing the square and im at (x+1)squared equals the square root of 5 fourths what do i do next.
(x + 1)^2 = √(5/4) take the square root of both sides.....remember that, on the right side, we have to take both roots.....so we have....
x + 1 = ±√(√(5/4) which we can simplify to....
x + 1 = ± 4√(5/4) subtract 1 from both sides
x = -1 ± 4√(5/4)
