Multiply the binomial and the trinomial. <br> (x-2)(x^2+2x+4)
malfutka [58]

Answer:

Step-by-step explanation:

To solve this problem, we need to multiple x and -2 by x^{2} + 2x + 4 and add the results together:

x(x^{2} + 2x + 4)

x^{3} + 2x^{2} + 4x

-2(x^{2} + 2x + 4)

-2x^{2} - 4x - 8

Adding the two together give the following:

(x^{3} + 2x^{2} + 4x) + (-2x^{2} - 4x - 8)

x^{3} - 8
