Solved by pluggable solver: SOLVE quadratic equation with variable

Quadratic equation $\"ax%5E2%2Bbx%2Bc=0\"$ (in our case $\"1x%5E2%2B10x%2B25+=+0\"$ ) 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 $\"b%5E2-4ac\"$ : $\"b%5E2-4ac=%2810%29%5E2-4%2A1%2A25=0\"$ .
\n" ); document.write( "
\n" ); document.write( " Discriminant d=0 is zero! That means that there is only one solution: $\"x+=+%28-%2810%29%29%2F2%5C1\"$ .
\n" ); document.write( " Expression can be factored: $\"1x%5E2%2B10x%2B25+=+1%28x--5%29%2A%28x--5%29\"$
\n" ); document.write( "
\n" ); document.write( " Again, the answer is: -5, -5.\n" ); document.write( "Here's your graph:
\n" ); document.write( " $\"graph%28+500%2C+500%2C+-10%2C+10%2C+-20%2C+20%2C+1%2Ax%5E2%2B10%2Ax%2B25+%29\"$
