I'm not 100% sure, but I am almost certain that you add your like terms on the left side. This will give you -14n+1>1. Next you want to solve like any other equation. subtract the 1 to the other side, -14n>2. Now, divide by -14. Since you are dividing, you want to flip the sign, so it says n<-1/2. That should be it. I really hope you get this right, and if you don't I'm sorry. It's been a while since I've done this kind of math.

Mrrafil [7]

First put it in standard form:
<span>x^2 −14x -15 =0
a =1 b =-14 c=-15
Then use the quadratic formula:
x = [-b +-sq root (b^2 - 4ac)] / 2a
x = [--14 +- sq root (14^2 -4*1*-15] / 2*1
x = [14 +-sq root (196 +60)] / 2
</span><span>x = [14 +- 16] / 2
x1 = 15
x2 = -1

</span>
