x=4 z=117
Step-by-step explanation:
Answer:
answer what?
Step-by-step explanation:
The most general proccedure for this type of problems is the following:
For a quadratic function of the following form
; where b and c are real numbers.
1) Identify the value that accompanies the x, that is, the value "b"
2) Divide the value of b by 2 and then square it: 
3) Add and subtract in the function the value of 
4) Write the complete function of the form
For the function presented
the result is as follows:
1) The value of b is 12
2) 
3) 
4)
Finally the function is:

The zero pair that must be added is 36 and -36
I’m pretty sure it is 66 since the base would be congruent to the top so plug in 7 into 10u-4 and u get 66!! (You plug in 7 since u=7)
