Question

Write all the factors of the expression obtained by subtraction of $-3x^2{y}^2$ from $x^2{y}^2$.

Answer 1

$x^2{y}^2-(-3x^2{y}^2)=x^2{y}^2+3x^2{y}^2=4x^2{y}^2$
$4x^2{y}^2=1\times 2\times 2\times x\times x\times y\times y$

Factors of $4x^2{y}^2$ are $1$, $2$, $4$, $x$, $2x$, $4x$, $y$, $2y$, $4y$, $x^2$, $2x^2$, $4x^2$, $y^2$, $2y^2$, $4y^2$, $xy$, $2xy$, $4xy$, $x{y}^2$, $2x{y}^2$, $4x{y}^2$, $x^{2}y$, $2x^{2}y$, $4x^{2}y$, $x^2{y}^2$, $2x^2{y}^2$, and $4x^2{y}^2$.
