Solved by pluggable solver: SOLVE quadratic equation (work shown, graph etc)
Quadratic equation \"ax%5E2%2Bbx%2Bc=0\" (in our case \"1x%5E2%2B-12x%2B-5+=+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=%28-12%29%5E2-4%2A1%2A-5=164\".
\n" ); document.write( "
\n" ); document.write( " Discriminant d=164 is greater than zero. That means that there are two solutions: \"+x%5B12%5D+=+%28--12%2B-sqrt%28+164+%29%29%2F2%5Ca\".
\n" ); document.write( "
\n" ); document.write( " \"x%5B1%5D+=+%28-%28-12%29%2Bsqrt%28+164+%29%29%2F2%5C1+=+12.4031242374328\"
\n" ); document.write( " \"x%5B2%5D+=+%28-%28-12%29-sqrt%28+164+%29%29%2F2%5C1+=+-0.403124237432849\"
\n" ); document.write( "
\n" ); document.write( " Quadratic expression \"1x%5E2%2B-12x%2B-5\" can be factored:
\n" ); document.write( " \"1x%5E2%2B-12x%2B-5+=+%28x-12.4031242374328%29%2A%28x--0.403124237432849%29\"
\n" ); document.write( " Again, the answer is: 12.4031242374328, -0.403124237432849.\n" ); document.write( "Here's your graph:
