Question

factorise the following expression X2+12x+27

Answer 1

Concept

Factorisation of any polynomial is the process by which the original polynomial is broken into its factor such that when these factors are multiplied it gives the original polynomial.

Given

The given polynomial is x**2 + 12x + 27.

Find

We have to calculate the factor of the given polynomial.

Solution

Find the integers such that when these are added it gives 12 and when multiplied then it gives 27.

x**2 + 12x + 27

= x**2 + 9x + 3x + 27

= x(x + 9) + 3(x + 9)

=(x + 9)(x + 3)

Hence the factors of the given polynomial is (x + 9)(x + 3).
