Answer
$x^3-4x^2+9x+7$
Work Step by Step
Subtract each term of the subtrahend then simplify by combining like terms to obtain:
$(x^3-2x^2+5x+10)-(2x^2-4x+3)\\
=x^3-2x^2+5x+10-2x^2-(-4x)-3\\
=x^3-2x^2+5x+10-2x^2+4x-3\\
=x^3-(2x^2+2x^2)+(5x+4x)+(10-3)\\
=x^3-4x^2+9x+7$
Hence, the single polynomial answer in standard form is $x^3-4x^2+9x+7$.
