Expand and simplify (p+7) (p-8)

P^2-8p+7p-56

First I foiled. This meaning that I multiplied the first numbers in each pair of parentheses, then I multiplied the outside numbers, then the inside numbers and finally the last numbers.

p^2-p-56

Second I combined like factors.

This should be your final answer, keep in mind that ^2 means squared.

p^2-p-56
