You can put this solution on YOUR website!
It can't be factored so you either have to complete the square or use the quadratic formula

Solved by pluggable solver: SOLVE quadratic equation with variable
Quadratic equation \"ax%5E2%2Bbx%2Bc=0\" (in our case \"16x%5E2%2B56x%2B49+=+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=%2856%29%5E2-4%2A16%2A49=0\".
\n" ); document.write( "
\n" ); document.write( " Discriminant d=0 is zero! That means that there is only one solution: \"x+=+%28-%2856%29%29%2F2%5C16\".
\n" ); document.write( " Expression can be factored: \"16x%5E2%2B56x%2B49+=+16%28x--1.75%29%2A%28x--1.75%29\"
\n" ); document.write( "
\n" ); document.write( " Again, the answer is: -1.75, -1.75.\n" ); document.write( "Here's your graph:
\n" ); document.write( "\"graph%28+500%2C+500%2C+-10%2C+10%2C+-20%2C+20%2C+16%2Ax%5E2%2B56%2Ax%2B49+%29\"
\n" ); document.write( " \n" ); document.write( "
