Solved by pluggable solver: SOLVE quadratic equation with variable
Quadratic equation \"ax%5E2%2Bbx%2Bc=0\" (in our case \"3x%5E2%2B4x%2B-27+=+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=%284%29%5E2-4%2A3%2A-27=340\".
\n" ); document.write( "
\n" ); document.write( " Discriminant d=340 is greater than zero. That means that there are two solutions: \"+x%5B12%5D+=+%28-4%2B-sqrt%28+340+%29%29%2F2%5Ca\".
\n" ); document.write( "
\n" ); document.write( " \"x%5B1%5D+=+%28-%284%29%2Bsqrt%28+340+%29%29%2F2%5C3+=+2.40651481909763\"
\n" ); document.write( " \"x%5B2%5D+=+%28-%284%29-sqrt%28+340+%29%29%2F2%5C3+=+-3.73984815243096\"
\n" ); document.write( "
\n" ); document.write( " Quadratic expression \"3x%5E2%2B4x%2B-27\" can be factored:
\n" ); document.write( " \"3x%5E2%2B4x%2B-27+=+3%28x-2.40651481909763%29%2A%28x--3.73984815243096%29\"
\n" ); document.write( " Again, the answer is: 2.40651481909763, -3.73984815243096.\n" ); document.write( "Here's your graph:
