Question

factories;
I)( x3-4x)
ii)x4(x2-y2)÷(x+y)

Answer 1

$\huge\boxed{\texttt{\fcolorbox{red}{aqua}{Hey Mate!!!}}}$
I)
${x}^{3} - 4x \\ = x( {x}^{2} - 4) \\ = x( {x}^{2} - {2}^{2} ) \\ = x(x - 2)(x + 2)$
ii)
${x}^{4} ( {x}^{2} - {y}^{2} ) \div (x + y) \\ = \frac{ {x}^{4} (x + y)(x - y)}{(x + y)} \\ \\ = {x}^{4} (x - y)$


$\large{\red{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\boxed{\underline{\underline{\underline{Hope\:it\:helps\: you}}}}}}}}}}}}}}}$

Answer 2

(ii) x⁴(x²-y²)
x⁴(X+y)(x-y)/(X+y)
x⁴(x-y)
(I). (x³-4x)
X(x²-4)
X(x²-2²)
X(X+2)(x-2)
