Solve for x 9xsquared = 27
You need to divide by 9 both sides, such that:
`9x^2 = 27 => x^2 = 27/9 => x^2 = 3`
You need to take square root both sides, such that:
`sqrt(x^2) = sqrt 3 => |x| = sqrt 3 => x_(1,2) = +-sqrt3`
Hence, evaluating the solutions to the given equation, yields `x_(1,2) = +-sqrt3` .
