Which of the binomials below is a factor of this trinomial? x2 – 4x – 12 a. x – 6 b. x – 4 c. x – 2 d. x – 3

The answer is A.) x-6

The middle number is -4 and the last number is -12. Factoring means we want something like

(x+_)(x+_)

So which numbers go in the blanks??

We need two numbers that

- Add together to get -4

-Multiply together to get -12

Try 2 and -6:

2+-6 = -4

2*-6 = -12

This checks out!

Fill in the blanks in

(x+_)(x+_)

with 2 and -6 to get...

(x+2)(x-6)

Which means A is the answer :) Hope this helped you!

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
