Use any method to find the product
(x + 7)(x - 3)

x^2 +4x-21

Step-by-step explanation:

Just expand using FOIL (First, Outside, Inside, Last, I believe)

(x + 7) ( x - 3)  = x² + 4x - 21

Step-by-step explanation:

Using the FOIL method: (a + b) (c - d) = ac - ad + bc - bd

(x + 7) ( x - 3)

= x² - 3x + 7x - 21

Add like terms:

= x² + 4x - 21

Therefore, the product of the two binomials is: = x² + 4x - 21

part 1 answer = 8

part 2 answer = 72

step-by-step explanation:

part 1 explanation = add all of the numbers, then divide by how many numbers you have. so, 200/25 = 8.

part 2 explanation = not gonna lie, this is hard to explain, so just google how to do it.
