You can put this solution on YOUR website!
Maybe your EQUATIONS are these?
x%5E2%2B9x%2B3=0 and x%5E2-2x-11=0





-----------------------------------------------------------------------------
Here is a different but helpful example to learn from, using general quadratic formula solution:
x%5E2%2B8x%2B1=0
x=%28-8%2B-+sqrt%288%5E2-4%2A1%29%29%2F2
x=%28-8%2B-+sqrt%2864-4%29%29%2F2
and then continue to simplify and /or compute those.

They are not equations, at all.
