Answer:

y = - 4, y = 0

Step-by-step explanation:

Given

y² + 4y = 0 ← factor out y from each term on the left side

y(y + 4) = 0 ← in factored form

Equate each factor to zero and solve for y

y = 0

y + 4 = 0 ⇒ y = - 4

Answer:

y=0,y=-4

Step-by-step explanation:

y^2+4y=0

In this kind of question,you will have to look for what is common to the two figures

Then solve,it was observed that y is common to the two,then you will have to factorise

y(y+4)=0

Which means that y outside the bracket equals to 0

That is y=0

Let's move to the bracket

y+4=0

Substrate 4 from both sides y=-4

We were able to get to values for y

y=0,y=-4
