Q.2 (A)(i) Complete the following activity to solve the quadratic equation \(x^2 + 8x - 48 = 0\) by completing square method.
Activity :
\(\therefore\ x^2 + 8x - 48 = 0\)
\(\therefore\ x^2 + 8x + 16 -\) ____ \(- 48 = 0\)
\(\therefore\ (x + 4)^2 -\) ____ \(= 0\)
\(\therefore\ (x + 4)^2 = 64\)
\(\therefore\ x + 4 =\) ____ or \(x + 4 = -8\)
\(\therefore\ x = 4\) or \(x =\) ____
