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.
⇒ x2 – a2 – x – a = 0
⇒ (x + a)(x – a) – 1(x + a) = 0
⇒ (x + a)(x – a – 1) = 0
⇒ x = -a, a + 1
