(-7+p)(8+p)

To calculate the product of the two binomials, you need to use the distributive property.

First, we will multiply the first term of the first binomial (-7) by both terms in the second binomial (8 and p):
-7 * 8 = -56
-7 * p = -7p

Next, we multiply the second term of the first binomial (p) by both terms in the second binomial:
p * 8 = 8p
p * p = p^2

Now, we combine all these products to simplify the expression:
(-7 + p)(8 + p) = -56 -7p + 8p + p^2

Simplifying further, we can combine like terms (-7p and 8p) to get:
(-7 + p)(8 + p) = -56 + p + p^2

Therefore, the simplified expression for (-7 + p)(8 + p) is -56 + p + p^2.
