%287x%5E3+%2B+4x%29%28x%5E2+%2B+2%29
Use the FOIL method,
First : %287x%5E3%29%28x%5E2%29=7x%5E5
Outer : %287x%5E3%29%282%29=14x%5E3
Inner : %284x%29%28x%5E2%29=4x%5E3
Last : %284x%29%282%29=8x
%287x%5E3+%2B+4x%29%28x%5E2+%2B+2%29=7x%5E5%2B14x%5E3%2B4x%5E3%2B8x
%287x%5E3+%2B+4x%29%28x%5E2+%2B+2%29=7x%5E5%2B18x%5E3%2B8x
