Question

Factorise:
Xcube+x_3xsquare_3

Answer 1

Answer:

(x² + 1)(x - 3)

Solution:

Here,

The given cubic polynomial is ;

x³ + x - 3x² - 3 .

We need to factorize the given cubic polynomial .

Thus,

Here we go ↓

=> x³ + x - 3x² - 3

=> x(x² + 1) - 3(x² + 1)

=> (x² + 1)(x - 3)

Hence,

Required answer is (x² + 1)(x - 3) .
