Find factored form of -7y-y^2=0

-y(y + 7) = 0

y = 0

y = -7

Step-by-step explanation:

-7y – y^2=0

y(-7-y) = 0

[y can be factored out because -7y and y² are both multiplied by y, -7y and -y² = -7(y) and -y(y). They have a common variable factor of y]

-y(7 + y) = 0

[-1 can also be factored out because -7 and -y both have a negative]

-y(7 + y) = 0 → -y = 0 and (7 + y) = 0.

-y = 0 → -y÷-1 = 0÷-1 → y = 0

(7 + y) = 0 → 7 + y – 7 = 0 – 7 → y = -7

the correct answer is 5
