Answer:
y = -3,-4
Step-by-step explanation:
Factor the equation, which gives you (y+3)(y+4)=0
Then, all you do is find the values that give the equation an answer of 0.
Since anything times 0 is 0, all you have to do is make one of the (y+x) values equal 0.
Since -3 and -4 added to 3 and 4 make 0 the answers are -3 and -4.
You can check by plugging it back into the equation or graphing it.
