2n^2 + 4n = 0

divide through by 2

n^2 + 2n = 0

factor out n

n(n+2) = 0

n=0 or n+2 =0

Answers: n = 0 or n = -2

Hi Tahlia,

To solve this equation you will need to simplify the equation by determining the greatest common factor and then solving for n.

To solve this equation you will need to simplify the equation by determining the greatest common factor and then solving for n.

2n^{2 }+ 4n = 0 (the greatest common factor among 2n^{2} and 4n is 2n)

=> 2n(n + 2) = 0.

Now solve for n:

2n = 0 => **n = 0** OR

n + 2 = 0 => **n = -2**

Hope this helps!

Thanks :)
