Answer:

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
