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.
⇒ 2x2 – 9 + 3x = 3x2 – 14 –x
⇒ x2 – 4x – 5 = 0
⇒ x2 – 5x + x – 5 = 0
⇒ (x – 5)(x + 1) = 0
⇒ x = -1, 5
