SOLUTION: I'm working on solving polynomial equations. I'm stuck on this one. It isn't in the book. 2x^2 = 18 I figure that you would divide by 2 first but I'm not sure what to do next.

Sure Anne,
Divide it by 2 ,then take the square root to get the value of x,
2x^2=18
X^2=18/2
X^2=9
X=square root 9
X=3
Simply to check:
2(3)^2=18
18=18 sweet!
