Factorize each of the following expressions:$8x^2y^3 - x^5$
Given:
$8x^2y^3 - x^5$
To do:
We have to factorize the given expression.
Solution:
We know that,
$a^3 + b^3 = (a + b) (a^2 - ab + b^2)$
$a^3 - b^3 = (a - b) (a^2 + ab + b^2)$
Therefore,
$8x^2y^3 - x^5 = x^2(8y^3 - x^3)$
$= x^2[(2y)^3 - (x)^3]$
$= x^2[(2y - x) (2y)^2 + 2y \times x + (x)^2]$
$= x^2(2y - x) (4y^2 + 2xy + x^2)$
Hence, $8x^2y^3 - x^5 = x^2(2y - x) (4y^2 + 2xy + x^2)$.
