Question 1086605
.
Given Quadratic Equations have positive and negative solutions, solve the following and list negative solutions:


<pre>
a) n^2+(n+1)^2=13     ---->  Negative solution is n = -3.

b) n+(n+1)(n+2)=14    ---->  n^2 + 4n - 12 = 0  --->  negative solution is n= -6.

c) n(n+2)+n+5=15      ---->  n*(n+2) + n = 15-5 = 10   ---->  n*(n+3) = 10  --->  negative solution is n = -5.
</pre>
