You can put this solution on YOUR website!
the solutions of a general quadratic equation ax%5E2%2Bbx%2Bc are given by the quadratic formula
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
in your question x^2+6x=-3 that is x^2+6x+3=0
we have a=1, b=6, c=3
so the solutions are x=%28-6+%2B-+sqrt%2836-4%2A1%2A3%29%29%2F2+

=>+x=%28-6+%2B-+sqrt%2824%29%29%2F2+
=>+x=%28-6+%2B-+2sqrt%286%29%29%2F2+
=>+x=%28-3+%2B-+sqrt%286%29%29+
