This is actually a mental problem you can solve in seconds while remembering \"ax%5E2%2Bbx%2Bc\"
\n" ); document.write( "\"x%5E2-x-56=0\" find 2 numbers that add to (b) and multiply to get (c)
\n" ); document.write( "-8 and 7
\n" ); document.write( "Now take the opposite of those numbers to find what x is equal too
\n" ); document.write( "X= 8,-7
\n" ); document.write( "
