Solve \"+2x%5E3%2B7x%5E2-12x-45=0\"\r
\n" ); document.write( "\n" ); document.write( " Factor 2x^3+7x^2-12x-45
\n" ); document.write( " =\"+2x%5E2%28x+%2B+3%29+%2B+x%5E2+-+12+x+-45\"
\n" ); document.write( " = \"+2x%5E2%28x+%2B+3%29+%2B+%28x+%2B3%29%28x-15%29\"
\n" ); document.write( " = \"+%28x%2B3%29%282x%5E2+%2B+x+-15%29+\"
\n" ); document.write( " = \"%28x%2B3%29%28x%2B3%29+%282x+-5%29+\"
