Question

Find the sum of these polynomials.(x²-x+ 8) + (10x² + 7) =A. 11x²-x+1B. 10x²-x+1 c. 11x²-x+15D. 10x²-x+ 15

Answer 1

`c)\text{ }11x^2-x+15`Step-by-step explanation

Step 1

given

`(x^2-x+8)+(10x^2+7)`

a): Group the like terms. Like terms are terms whose variables and exponents are the same

so

`\begin{gathered} (x^2-x+8)+(10x^2+7) \\ x^2-x+8+10x^2+7 \\ (x^2+10x^2)+(-x)+(8+7) \end{gathered}`

b)Simplify by combining like terms.

`\begin{gathered} (x^(2)+10x^(2))+(-x)+(8+7) \\ 11x^2-x+15 \end{gathered}`

therefore, the answer is

`c)\text{ }11x^2-x+15`

I hope this helps you
