(x + 1)(x^2 + 1)
First multiply the x in the first set of parentheses times everything in the second, then multiply the 1 in the first set of parentheses times everything in the second:
x%28x%5E2%2B1%29%2B1%28x%5E2%2B1%29
x%28x%5E2%29%2Bx%281%29%2B1%28x%5E2%29%2B1%281%29
x%5E3%2Bx%2Bx%5E2%2B1 We usually write this in descending order.
highlight%28x%5E3%2Bx%5E2%2Bx%2B1%29
