Question 148970: The problem is:
3x^2+5=11
I started by subtracting 11 from both sides to turn the equation into:
3x^2+5-11=0
I believe I then have to factor but im not sure how? What would be the next step if the above is correct?

3x^2+5-11=0

Combine like terms
3x^2-6=0

Factor out a 3
3(x^2-2)=0

Set x^2-2 equal to zero
x^2-2=0

So x^2=2
So x=sqrt%282%29
