Answer 3

Factor,
x^2+12x+20=0
(x+10)(x+2)=0
x+10=0, x+2=0
x=-10, -2.
Answer: -10, -2.
The key here is to find 2 numbers that when they multiply, you get the third term and when you add them, you get the second term. So for this problem, these 2 numbers are 10 and 2. Because 10 times 2 gives you 20 and 10+2=12.
