Hi! I hope you're enjoying your day!

Let's add the following polynomials.

How to add them? Just combine like terms. :)

$\bold{2x^2-10x+1 ~and~x^2+15x-8}$

$\bold{2x^2+x^2-10x+15x+1-8}$

Hence, the answer is

$\boxed{\boxed{\bold{3x^2+5x-7}}}$

$\rule{250}{2}$

$\bold{2x^3-3x^2+5\;and\;5x^2-3x^3+7}}}\\$

Combine Like terms:

$\bold{2x^3-3x^3-3x^2+5x^2+5+7}$

Hence, the answer is

$\boxed{\boxed{\bold{-x^3+2x^2+12}}}$

Hope everything is clear.
