Question 686861
You mistakenly did this


3(-1)^2-5(-1)+4


3(1)-5(1)+4


3 - 5 + 4


-2 + 4


2


This is NOT the correct answer


-------------------------------------------------------


Here's what you *should* do


3(-1)^2-5(-1)+4


3(1)-5(-1)+4


3 + 5 + 4


8 + 4


12


So 3(-1)^2-5(-1)+4 = 12, which means that 12 is the correct answer.
