(y + 9) (y + 4) = 0
y =

Answer 1

Answer:
`y = -9, -4`

Explanation:

the given equation is asking whether a product of two terms is equal to zero, and it only could happen if at least one of the two terms is zero, it means:

`y+9=0\\or\\y+4=0`

And finally, trasposing the constants, we would get:

`y=-9\\or\\y=-4`
