Solve the following quadratic equations by factorization:

In factorization, we write the middle term of the quadratic equation either as a sum of two numbers or difference of two numbers such that the equation can be factorized.

⇒ 3(9x² + 1 – 6x) – 2(4x² + 9 + 12x) = 5(6x² – 3 + 7x)

⇒ 11x² + 77x = 0

⇒ 11x(x + 7) = 0

⇒ x = 0, - 7
