0 = 3x^2-5x-5
\n" ); document.write( "the quadratic formula gives us
\n" ); document.write( "x = (5+square root(85)) / 6 = 2.369924076
\n" ); document.write( "x = (5-square root(85)) / 6 = −0.70325741
\n" ); document.write( "there are two real number solutions to the equation
\n" ); document.write( "***************************************************
\n" ); document.write( "substitute each solution in the original equation
\n" ); document.write( "(3×(2.369924076)^2)−(5×2.369924076)−5 = −0.000000002
\n" ); document.write( "(3×(−0.70325741)^2)−(5×−0.70325741)−5 = 0.000000004
