Math Problem Statement

(x - 7)(x + 2)

Solution

To simplify the expression (x7)(x+2)(x - 7)(x + 2), we apply the distributive property (also known as FOIL: First, Outer, Inner, Last) to multiply the terms.

(x7)(x+2)=x(x+2)7(x+2)(x - 7)(x + 2) = x(x + 2) - 7(x + 2)

Now, distribute each term:

=x2+2x7x14= x^2 + 2x - 7x - 14

Combine like terms:

=x25x14= x^2 - 5x - 14

So, (x7)(x+2)=x25x14(x - 7)(x + 2) = x^2 - 5x - 14.
