If t = - 3, then 3t2 + 5t+6 equals

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.
