You can put this solution on YOUR website!
x^2-4x-15=0 using the quadratic equation: $\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"$
\n" ); document.write( "x=(4+-sqrt[-4^2-4*1*-15])/2*1
\n" ); document.write( "x=(4+-sqrt[16+60])/2
\n" ); document.write( "x=(4+-sqrt76)/2
\n" ); document.write( "x=(4+-8.72)/2
\n" ); document.write( "x=(4+8.72)/2
\n" ); document.write( "x=12.72/2
\n" ); document.write( "x=6.36 answer.
\n" ); document.write( "x=(4-8.72)/2
\n" ); document.write( "x=-4.72/2
\n" ); document.write( "x=-2.36 answer.
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "x^2+8x-33=0
\n" ); document.write( "(x+11)(x-3)=0
\n" ); document.write( "x+11=0
\n" ); document.write( "x=-11 answer.
\n" ); document.write( "x-3=0
\n" ); document.write( "x=3 answer.
