What level of math are you trying to be good at?
Step-by-step explanation:
step 1: if t=-3 then add it in
3(-3)2+5(-3)+6
Step 2: -solve what's in the ()'s
3(-3)=9 & 5(-3)= -15
-then add them to the equation
(9)2-15+6=?
step 3: -solve like how you did in step 2
(9)2=18 & -15+6=-9
-then add it to the equation
18-9=?
step 4: Finish solving!
it equals 9
So 9 would be your answer.
