Question

Simplify the following expression: (x^5+x^4+x+10)-(x^5+2x^4-x^3+12). Express your answer as a polynomial with the degrees of the terms in decreasing order.

Accepted Answer

We have align* &(x^5+x^4+x+10)-(x^5+2x^4-x^3+12) &=(1-1)x^5+(1-2)x^4+(0-(-1))x^3+(1-0)x+(10-12) &=-x^4+x^3+x-2 align*
