Find the missing factor.<br> 8x^2 - 15x + 7 = (8x - 7)( )
Leokris [45]

Answer:

Step-by-step explanation:

(8x - 7)(

The x^2 term has to come out to 8x^2.

The 8 is already there.

So your first term in the second factor is x.

(8x - 7) ( x

Now the question is what is the sign after the x. Since the question shows +7 the only way that can happen is if both signs in the factors are the same.

Since (8x - 7) has been given to you and you need 7 to come out plus, then the sign after x must minus. Both signs must be the same.

(8x - 7)(x -

Last, what comes after the minus sign? You already have a minus 7 so you need something to multiply by 7 to get seven.

That should be a one.

(8x - 7)(x - 1)

x - 1 is you answer. I leave you to check the middle term. It is - 15
