Question

Evaluate x*2-(y-2) squared when y=3 and x=3? I got seven, but I don't believe that is right.

Answer 1

\[x^2-(y-2)\] replace and get
\[3^2-(3-2)=9-1=8\]

Answer 2

do math in this order: brackets > multiply and divide > add and minus

Answer 3

oh wait, is it
\[x^2-(y-2)^2\]?

Answer 4

no matter it is 8 in that case too

Answer 5

it's\[2x - (y-2)\]
