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

⇒ 5x(4x – 8 + 3x + 3) = 46(x + 1)(x – 2)

⇒ 35x² – 25x = 46x² – 92 – 46x

⇒ 11x² - 19x - 92 = 0

⇒ 11x² - 44x + 23x – 92 = 0

⇒ 11x(x – 4) + 23(x – 4) = 0

⇒ (11x + 23)(x – 4) = 0

⇒ x = 4, - 23/11
