Question

2x(5-x)+3x^2 shown work please

Answer 1

$\\ \rm\Rrightarrow 2x(5-x)+3x^2$

$\\ \rm\Rrightarrow 10x-2x^2+3x^2$

$\\ \rm\Rrightarrow 10x+(-2+3)x^2$

$\\ \rm\Rrightarrow 10x+x^2$

$\\ \rm\Rrightarrow x^2+10$

Answer 2

2x(5－x)＋3x²
＝x(2(5－x)＋3x)
＝x(10－2x＋30x)
＝x(10＋x)

OR

2x(5－x)＋3x²
＝10x－2x²＋3x²
＝10x＋x²

Hope my answer helped u :)
