Answer 2

Answer:–

$=\:2x²\: -\:16x$

Explanation:—

$10x\: [\dfrac{x²\: -\:13x\:+\:40}{5(x\: -\:5)} ]$

$10x\: [\dfrac{x²\: -\:8x\: -\:5x\: +\:40}{5x \: -\:25}]$

$10x\:[ \dfrac{x(x\: -\:8)\: -4\:(x\: -\:8)}{5(x\: -\:5)} ]$

$\dfrac{10x}{5}\:[\dfrac{(x\: -\:8)(x\: -\:5)} ]$

$=\: 2x\: (x\: -\:8)$

$=\:2x²\: -\:16x$
