Solve the given quadratic equation by factorization method x2 – 13x – 30 = 0

ii. Solve the given quadratic equation by factorization method 
x2 – 13x – 30 = 0


Ans. x2 – 13x – 30 = 0
x2 – 15x + 2x – 30 = 0
x(x – 15) + 2(x – 15) = 0
(x – 15) (x + 2) = 0
(x – 15) = 0      OR    (x + 2 ) = 0

x = 15    or    x = - 2
