Hi Tahlia,

To solve this equation you will need to simplify the equation by determining the greatest common factor and then solving for n.
 
2n+ 4n = 0 (the greatest common factor among 2n2 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!
