\"3x%5E2+=+2x+%2B+5\"
\n" ); document.write( "\"3x%5E2+-+2x+-5+=+0\"
\n" ); document.write( "\"%283x-5%29%28x%2B1%29=0\"
\n" ); document.write( "so either (3x-5)=0 or (x+1)=0 , which means roots are 5/3 and -1\r

Solved by pluggable solver: SOLVE quadratic equation with variable
Quadratic equation \"ax%5E2%2Bbx%2Bc=0\" (in our case \"3x%5E2%2B-2x%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=%28-2%29%5E2-4%2A3%2A-5=64\".
\n" ); document.write( "
\n" ); document.write( " Discriminant d=64 is greater than zero. That means that there are two solutions: \"+x%5B12%5D+=+%28--2%2B-sqrt%28+64+%29%29%2F2%5Ca\".
\n" ); document.write( "
\n" ); document.write( " \"x%5B1%5D+=+%28-%28-2%29%2Bsqrt%28+64+%29%29%2F2%5C3+=+1.66666666666667\"
\n" ); document.write( " \"x%5B2%5D+=+%28-%28-2%29-sqrt%28+64+%29%29%2F2%5C3+=+-1\"
\n" ); document.write( "
\n" ); document.write( " Quadratic expression \"3x%5E2%2B-2x%2B-5\" can be factored:
\n" ); document.write( " \"3x%5E2%2B-2x%2B-5+=+3%28x-1.66666666666667%29%2A%28x--1%29\"
\n" ); document.write( " Again, the answer is: 1.66666666666667, -1.\n" ); document.write( "Here's your graph:
