Multiply the polynomial expression (x+2)(x−4)

2 answers

To multiply the polynomial expression (x+2)(x-4), we can use the distributive property:

(x+2)(x-4) = x(x-4) + 2(x-4)

Using the distributive property again, we get:

x(x-4) + 2(x-4) = x*x - 4*x + 2*x - 8

Simplifying further:

x*x - 4*x + 2*x - 8 = x^2 - 2*x - 8

Therefore, the product of the polynomial expression (x+2)(x-4) is x^2 - 2*x - 8.
