Factor x2 – 2x – 80.

A. (x – 3)(x + 10)
B. (x + 6)(x - 1)
C. (X + 8)(x - 10)
D. (+3)(x+6)

(x-10) (x+8)

Step-by-step explanation:

x^2 – 2x – 80.

What two numbers multiply to -80 and add to -2

-10*8 = -80

-10+8 = -2

(x-10) (x+8)

Explanation:

The last term is -80 and the middle coefficient is -2

Find two numbers that

Those two numbers are 8 and -10

which is why the original expression factors to (x+8)(x-10)

We can use the FOIL rule to expand out (x+8)(x-10) to end up with x^2-10x+8x-80 = x^2-2x-80, which confirms we have the correct factorization. You can use the box method as an alternative.

the correct answers i think are b. and d.

give me brainliest if it is correct!
