Deirdre is factoring the polynomial x2 + 2x - 24. Which combination can she use to replace the middle term, 2x?

to replace 2x we need + 6x-4x

6x - 4x

Step-by-step explanation:

x^2 + 2x - 24

We need to find out the factors that replace the middle term + 2x

Constant term is - 24

coefficient of middle term is + 2

We need to find out two factors whose product is - 24 and sum is + 2

6 times (-4) = - 24

6 + (-4) = 2

So 6 and - 4 gives us product - 24 and sum + 2

the middle term + 2x can be written as 6x - 4x
