z² + 7z = 0
give the values of a,b,and c for each equation (rewrite each equation in the
form ax² + bx + c = 0 if necessary thanks so much for the help!!!


To make it in that form, write the corresponding terms of your equation
and ax² + bx + c = 0 so that they line up vertically like this:

ax² + bx + c = 0
 z² + 7z     = 0

Then put a "1" before the "z²" underneath the "a" and "+ 0" underneath the "+ c"

ax² + bx + c = 0
1z² + 7z + 0 = 0

And we see that a = 1, x = z, b = 7, and c = 0
