Solved by pluggable solver: SOLVE quadratic equation with variable
Quadratic equation \"ax%5E2%2Bbx%2Bc=0\" (in our case \"3x%5E2%2B-11x%2B-6+=+0\") has the following solutons:
\n" ); document.write( "
\n" ); document.write( " \"x%5B12%5D+=+%28b%2B-sqrt%28+b%5E2-4ac+%29%29%2F2%5Ca\"
\n" ); document.write( "
\n" ); document.write( " For these solutions to exist, the discriminant \"b%5E2-4ac\" should not be a negative number.
\n" ); document.write( "
\n" ); document.write( " First, we need to compute the discriminant \"b%5E2-4ac\": \"b%5E2-4ac=%28-11%29%5E2-4%2A3%2A-6=193\".
\n" ); document.write( "
\n" ); document.write( " Discriminant d=193 is greater than zero. That means that there are two solutions: \"+x%5B12%5D+=+%28--11%2B-sqrt%28+193+%29%29%2F2%5Ca\".
\n" ); document.write( "
\n" ); document.write( " \"x%5B1%5D+=+%28-%28-11%29%2Bsqrt%28+193+%29%29%2F2%5C3+=+4.1487406649083\"
\n" ); document.write( " \"x%5B2%5D+=+%28-%28-11%29-sqrt%28+193+%29%29%2F2%5C3+=+-0.482073998241634\"
\n" ); document.write( "
\n" ); document.write( " Quadratic expression \"3x%5E2%2B-11x%2B-6\" can be factored:
\n" ); document.write( " \"3x%5E2%2B-11x%2B-6+=+3%28x-4.1487406649083%29%2A%28x--0.482073998241634%29\"
\n" ); document.write( " Again, the answer is: 4.1487406649083, -0.482073998241634.\n" ); document.write( "Here's your graph:
