Square root both side
Explanation:
I want to expand the squared term, so to do that I'll first multiply both sides by 2:
I don't see any easy factors, so let's use the quadratic formula. The general formula is:
and relates to a trinomial this way:
And we can see these two solutions in the graphing of both sides of the original equation:
graph{(y-(1/2)(x+8)^2)(y-0x-14)=0 [-16.69, 3.31, 9.14, 19.136]}
