Step-by-step explanation:
This is the equation that you started off with:
(x - z - )(x + z + )
You can't really use FOIL on this because that's used in multiplying binomials, and this is a trinomial, but you can still break it up and simplify it this way:
(a + b + c)*(d + e + f) = (a(d + e +f)) + (b(d + e + f)) + (c(d + e + f))
So, applying that idea to the actual equation:
x(x + z + ) -z(x + z + ) - (x + z + )
= x^2 + xz + x -xz -z^2 - z - x - z - 5
= x^2 - z^2 - 2z - 5
