Question

help!!!!!!!!!!! If one factor of x2 + 2x – 24 is (x+6), what is the other factor?

(x+8)
(x–8)
(x+4)
(x−4)

Answer 1

Answer:

the other factor is (X-4)

Step-by-step explanation:

this is a perfect square trinomial so the two factors should interact the next way:

x2 + 2x – 24

(X+6) * (X-4)     the two numbers added give you the middle       .                                 .                        number  (2)

                       

                        and multiplied give you the final number (24)  so:

1)     +6-4 =  2

and

2)     +6 * - 4  =  -24

Answer 2

x^2 + 2x -24

So I know one factor is gonna be 6. I have to find a number that multiply with 6 is equal -24. But when 6 add that number the answer must equal 2.

So as you can see 6 multiply -4 is -24. 6+ (-4) is 2z

The answer is D. (X-4)

Hope this helps!
