\n" ); document.write( "Hi,
\n" ); document.write( "*Note: format of a line for using the quadratic equaton
\n" ); document.write( "ax^2 + bx + c = 0
\n" ); document.write( "x^2 + 15x + 56=0 (given in the necessary format, no preliminary steps need to be taken)
\n" ); document.write( "a = 1 b = 15 and c = 56
\n" ); document.write( "Using the quadratic formula to solve the equation.
\n" ); document.write( " \"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "\"x+=+%28-15+%2B-+sqrt%28+15%5E2-4%2A1%2A56+%29%29%2F%282%29+\"
