Solved by pluggable solver: SOLVE quadratic equation with variable
Quadratic equation \"ay%5E2%2Bby%2Bc=0\" (in our case \"3y%5E2%2B4y%2B0+=+0\") has the following solutons:
\n" ); document.write( "
\n" ); document.write( " \"y%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%2A0=16\".
\n" ); document.write( "
\n" ); document.write( " Discriminant d=16 is greater than zero. That means that there are two solutions: \"+x%5B12%5D+=+%28-4%2B-sqrt%28+16+%29%29%2F2%5Ca\".
\n" ); document.write( "
\n" ); document.write( " \"y%5B1%5D+=+%28-%284%29%2Bsqrt%28+16+%29%29%2F2%5C3+=+0\"
\n" ); document.write( " \"y%5B2%5D+=+%28-%284%29-sqrt%28+16+%29%29%2F2%5C3+=+-1.33333333333333\"
\n" ); document.write( "
\n" ); document.write( " Quadratic expression \"3y%5E2%2B4y%2B0\" can be factored:
\n" ); document.write( " \"3y%5E2%2B4y%2B0+=+3%28y-0%29%2A%28y--1.33333333333333%29\"
\n" ); document.write( " Again, the answer is: 0, -1.33333333333333.\n" ); document.write( "Here's your graph:
\n" ); document.write( "\"graph%28+500%2C+500%2C+-10%2C+10%2C+-20%2C+20%2C+3%2Ax%5E2%2B4%2Ax%2B0+%29\"
