Answer :
[tex]\\ \rm\Rrightarrow 2x(5-x)+3x^2[/tex]
[tex]\\ \rm\Rrightarrow 10x-2x^2+3x^2[/tex]
[tex]\\ \rm\Rrightarrow 10x+(-2+3)x^2[/tex]
[tex]\\ \rm\Rrightarrow 10x+x^2[/tex]
[tex]\\ \rm\Rrightarrow x^2+10[/tex]
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 :)
