iren [92.7K]

Answer:

(y+1)

Step-by-step explanation:

use quadratic formula.

you will get two values of y

y= 7/5 and y= -1

u can create factors using these values of y (making 0 subject)

like

for 7/5

7/5=y

7=5y

5y-7=0

zero becomes subject in such cases bcz there are no numbers left on that side

now for -1

-1=y

y+1=0

so your factors are 5y-7 and y+1
