I'm assuming that y2 means y^2 or y squared. In that case, your factors will be (6y+1) and (6y-1).
If 380 would be 100%
Then use rule of 3
380 ______ 100%
440 ______ y
380y = 440×100%
380y = 440 × 1
Dividing both the sides by 380
y = 440/380
y = 1,158
Let's multiplity "y" by 100
y = 115,8%
As we did have 100% initially
Then the increase will be
The increase = 115,8% -100%
= 15,8%
This would your answer
