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.

⇒ 2(x² - 2x + 1 + 4x² + 4x + 1) = 5(2x² – x – 1)

⇒ 10x² + 4x + 4 = 10x² – 5x – 5

⇒ 9x = -9

⇒ x = -1
