  Solve the Quadratic equation and find the values of x.   1)      x 2  – 45x + 324 = 0               solution: x 2 – 36x – 9x + 324 = 0 x(x-36)-9(x-36) = 0 (x-9) (x-36) = 0 x = 9, x = 36                      2)      x 2 – 11x – 28 = 0   Solution: x 2 – 11x – 28 = 0 x 2 – 4x – 7x – 28 = 0 x(x-4)-7(x-4) = 0 (x-7) (x-4) = 0 x = 7 x = 4   Please comment for doubts.
