Question

Multiply. (u+2)(u-5). Simplify your answer.

Answer 1

Answer: -u - 10

(u + 2)(u - 5) = 2u - 5u + 2u - 10 =
-u - 10 (it can be written also as: -1u - 10)

Answer 2

`\sf{u^2-3u-10}`

Explanation:

In order to simplify this expression, we are going to use the FOIL method.

(FOIL = first, outer, inner, last)

first

u * u = u²

outer

u * (-5) = -5u

inner

2 * u = 2u

last

2 * (-5) = -10

combine like terms

u² - 5u + 2u - 10

u² - 3u - 10
