Question 33636: This is the problem that I need help with:I have multiple choice answers to choose from but I cannot even find any problems in our book like this (I'm working on a take home quiz
5x(x here is squared)+12=0
Can you tell me how to type in equations such as squared, fractions, the radical symbol, etc? How do we do this? I'm new to this site.

You can put this solution on YOUR website!
5%28x%5E2%29+12 = 0
5%28x%5E2%29 = -12
%28x%5E2%29 = -12/5
square root both sides
x = sqrt%28-12%2F5%29
x = sqrt+%28i%5E2%2A4%2A3%2F5%29 ( since i%5E2+=+-1)
x = 2isqrt%283%2F5%29

You can see the source of the solution to know how to insert sqrt sign in your equation .
