What missing number would complete the factorization x^2- 7x + 10 = ( x - 5 ) ( x - ? )
a. 1
b. 2
c. 4
d. 5

Hey!

Hope this helps...

The Answer is B. 2

Because when you foil (x-5)(x-2), you get:

(x-5)(x-2)

x^2 - 5x - 2x + 10

x^2 -7x +10

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,
