What are the factors of x2 - 4x - 5? Check all that apply. x - 5 x - 2 x - 1 x + 1 x + 2 x + 5What side lengths should be used to model a rectangle with an area of x2 + 3x - 10 square units? x - 5 and x + 2 x - 2 and x + 5 x and x + 3 x + 3 and x - 10

1. (x - 5), (x + 1)

2. (x + 5), (x - 2)

Step-by-step explanation:

1. x^2 - 4x - 5

Find two numbers that both multiple to - 5 and add to - 4 (-5 and 1)

(x - 5), (x + 1)

2. x^2 - 3x - 10

--same concept for these question

What two numbers multiple to equal - 10 and add to equal 3?

5 and - 2

(x + 5), (x - 2)
