Question

. Simplify the following completely and show your work: (9x2 + 3x - 5) + (8x2 - x + 2)

Answer 1

We have to simplify the following expression:

$(9x^2+3x+5)+(8x^2-x+2)$

We can combine the like terms and simplify as:

$\begin{gathered} (9x^2+8x^2)+(3x-x)+(5+2) \\ 17x^2+2x+7 \end{gathered}$

Answer: 17x² + 2x + 7
