Take half of the middle coefficient.
Then square it.
-12/2 = -6
(-6)^2 = 36
c = 36
the additive inverse of -8 is 8
to find the additive inverse you just have to change the sign of the number
Step one. create a common denominator.
ex. 15
walnuts = 10/15 dried fruit= 9/15
so if you had 15/15 pounds of dried fruit you would need 16/15 pounds of walnuts
which is 1 1/15 pounds of walnuts
