(-7+p)(8+p)
I don't understand this at all.
To simplify the expression (-7+p)(8+p), you can use the distributive property.
First, distribute the -7 to both terms inside the parentheses:
(-7)(8) + (-7)(p)
This gives you -56 - 7p.
Next, distribute the p to both terms inside the parentheses:
(8)(p) + (p)(p)
This gives you 8p + p^2.
Now, you can combine the like terms:
-56 - 7p + 8p + p^2
Simplifying further, you get p^2 + p - 56.
So, the simplified expression is p^2 + p - 56.
