Question

I need ro know more about how to do this. can you help me out?

Answer 1

`-2w^2-5w+1`

1) Since we need to simplify this polynomial expression, we need to do it step by step:

`\begin{gathered} (-7w^2-2w-1)-(-5w^2+3w-2)\:Remove\:the\:Parentheses \\ -7w^2-2w-1-\left(-5w^2+3w-2\right) \\ -7w^2-2w-1+5w^2-3w+2\:Combine\:like\:terms,and\:numbers \\ -2w^2-5w+1 \\ \end{gathered}`

2) Thus the answer is -2w²-5w+1
