Answer: 4
Since we need to find the y, we're going to substitute the x's with the numbers in the x column.
Let's try to find the first y box.
We're going to substitute all of the x's with -0.5.
y = 4(-0.5)^2 - 8(-0.5) + 4
Now, we're just going to solve that.
-2^2 - 4 + 4
-2 squared is 4. It's a positive 4 because a negative times a negative is a positive.
4 - 4 + 4
= 4

Factor: 20k+50
since you see there is a multiple of 10 you can do…
10(2k+5)
next you look if you can factor anything else as you can see you cannot so…
10(2k+5) is you answer
