The method in which we reduce the bracket of a quadractic equation, instead of expanding the bracket and converting the equation to a product of factors which cannot be reduced further is known as factorization.
Factorisation can basically be known as the reverse function of multiplication.
Factorization of y3 + y - 2y2 – 2 is ⇒
y3 + y − 2y2 − 2
y3 − 2y2 + y − 2
= (y − 2) (y2 + 1)
