Given: X%5E2+-+6X+=+135
Rewrite the equation as X%5E2+-+6X+-+135+=+0
This equation can be foiled.
First find the factors of 135.
They are: 1,3,5,9,15,27,45,135
9 and 15 fit for this equation.
X%5E2+-+6X+-+135+=+%28X+%2B+9%29+%2A+%28X+-+15%29 These two equations are equal
Now %28X+%2B+9%29+%2A+%28X+-+15%29+=+0
We have 2 solutions
X + 9 = 0 or rewritten as X = -9
& X - 15 = 0 or rewritten as X = 15
