What is the missing value; 9 to 7 = 45 to

9 to 7 = 45 to 35..

Step-by-step explanation:

Given function:

to find x:

Therefore, x=35.

using the a-c method to factor the quadratic the factors of the product 3×1=3 which sum to -4 and -3 and -1 split the middle term using these terms .

3x² - 3x - x + 1

3x( x-1) -1 ( x-1 )

take out common factor ( x -1)

= (x-1) (3x-1)

3x²-4x+1 = (x-1) (3x-1)
