To solve 1-20, you plug in the number for the variable that the variable is equal to e.i. a) x = -3 so you plug -3 in every place there is an x
-2(-3)^2 - 3(-3) + 1
-2(9) +9 + 1
-18 +10
-8
The solution to a) is -8.

How long do you have now I can help you
Move a2 to the left side of the equation so you have c2-a2. then divide by 2 to get b by itself. you are left with c2-a2 all over 2. the 2s will cancel and you'll be left with c-a=b
Y=3
Simplify
Distribute
Combine like terms
Add 2y to both sides
Add 2 to both sides
Divide by 3 , both sides.
