Question

Evaluate the polynomial when x = -3:x2 + 2x-5

Answer 1

-2

Step-by-step explanation

`x^2+2x-5`

to evaluate when x=-3, replace the x value and operate

so

Step 1

replace the x , with the given value

`\begin{gathered} x^2+2x-5 \\ (-3)^2+2(-3)-5 \\ (-3\cdot-3)-6-5 \\ 9-6-5 \\ -2 \end{gathered}`

so, the answer is -2
