FACTORIZE 1




Factorize x2 - 5x - 14 = 0

solution

x2 - 5x - 14 = 0    we split -5x to get ( -7x + 2x)

( -7x + 2x) = -5x    and  ( -7x x 2x) = -14x2

x2 - 5x - 14 = 0   

(x2 -7x) + (2x - 14) = 0

x(x -7) + 2(x - 7) = 0

 (x -7)(x +2) = 0

x-7 = 0 or x + 2 = 0

x = 7 or x = -2

TRY THIS.....................

Factorize x2 - 5x - 14 = 0
