If
f%28x%29=2x%5E4%2Bx%5E3%2B3x%5E2%2B3x-5
and
g%28x%29=3x%5E4-2x%5E3%2B7x%5E2-5x%2B2
then
f%28x%29%2Bg%28x%29=2x%5E4%2Bx%5E3%2B3x%5E2%2B3x-5%2B3x%5E4-2x%5E3%2B7x%5E2-5x%2B2
f%28x%29%2Bg%28x%29=5x%5E4-x%5E3%2B10x%5E2-2x-3
and
f%28x%29-g%28x%29=2x%5E4%2Bx%5E3%2B3x%5E2%2B3x-5-%283x%5E4-2x%5E3%2B7x%5E2-5x%2B2%29
f%28x%29-g%28x%29=2x%5E4%2Bx%5E3%2B3x%5E2%2B3x-5-3x%5E4%2B2x%5E3-7x%5E2%2B5x-2
f%28x%29-g%28x%29=-x%5E4%2B3x%5E3-4x%5E2%2B8x-7
