Question

I need help on a math problem What is 2x^2-3x+2 when x = -5

Answer 1

Given the expression:

`2x^2-3x+2`

if x = -5, then, we have the following:

`\begin{gathered} x=-5 \\ \Rightarrow2(-5)^2-3(-5)+2=2(25)+15+2= \\ 50+17=67 \end{gathered}`

therefore, if x = -5, then the expression equals to 67
