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
