Factor: x² - 2x - 80
Lets look at all the answer choices, try them out, and see if they are correct.
A) (x+8)(x-10)
Simplify.
x²-10x+8x-80
Add like terms.
x²- 2x - 80
Look at the equation that you wanted factored. Is it equal to your answer for A? Yep! So, A) is your answer.
However, just to make sure, we will go through all of the other options.
B) (x-8)(x+10)
Simplify.
x²+10x-8x-80
Add like terms.
x² + 2x - 80
So, B is incorrect.
C) (x+6)(x-1)
Simplify.
x²-x+6x-6
Add like terms.
x² + 5x - 6
So, C is also incorrect.
D) (x+3)(x+6)
Simplify.
x² + 6x + 3x + 18
Add like terms.
x² + 9x + 18
So, D is incorrect.
So, our answer is A) (x+8)(x-10)
