Open in App

Solution

Factorize the polynomial:
$8 x^{3} + 36 x^{2} y + 54 x y^{2} + 27 y^{3} = {(2 x)}^{3} + {(3 y)}^{3} + 3 \times {(2 x)}^{2} \times (3 y) + 3 \times 2 x \times {(3 y)}^{2}$
use the identity $a^{3} + b^{3} + 3 a^{2} b + 3 a b^{2} = {(a + b)}^{3}$
$8 x^{3} + 36 x^{2} y + 54 x y^{2} + 27 y^{3} = {(2 x + 3 y)}^{3}$
Hence the factorized form of polynomial $8 x^{3} + 36 x^{2} y + 54 x y^{2} + 27 y^{3}$ is $(2 x + 3 y) (2 x + 3 y) (2 x + 3 y)$
