You can put this solution on YOUR website!
you just add together like terms
Example:%282x%5E2%2B2x%2B1%29%2B%283x%5E2%2Bx%2B5%29
look at individual terms2x%5E2%2B3x%5E2=5x%5E2
2x%2Bx=3xand1+5=6
put them back together
5x%5E2%2B3x%2B6notice the indices(power)does not change
Also this is a very simple example
with others take careful notice of signs
