Question

Simplify the following sum of polynomials completely ( - 12s raise to power 2 + 10s - 3) + ( 2s raise to power 2 - 12s - 2)

Answer 1

`-10s^2-2s-5`

Step-by-step explanation

Given

`\mleft(-12s^2+10s-3\mright)+\mleft(2s^2-12s-2\mright)`

removing the brackets, we have;

`-12s^2+10s-3+2s^2-12s-2`

collecting like terms, we have

`\begin{gathered} -12s^2+2s^2+10s-12s-3-2 \\ \end{gathered}`

adding similar terms, we have;

`-10s^2-2s-5`

The solution is

`-10s^2-2s-5`
