How do you solve the equation by using the square root property for the following problem;
3x^2=5

psymon · Answer

The best you could do is get x^2 by itself then square root both sides. Just know that when you take the square root of both sides, you must put plus or minus. If that makes sense.

kinda??? 
I was using a Calculator, and it gives me a large number with a decimal, with a minus and a plus in front of it, although it's not giving me the what I'm looking for...

psymon · Answer

Ah. Well, let's get x^2 by itself first by dividing both sides by 3:
$$x ^{2}=\frac{ 5 }{ 3 } $$
Then we would take the square root of both sides:

psymon · Answer

$$\sqrt{x ^{2}}=\sqrt{\frac{ 5 }{ 3 }}->x=\pm \sqrt{\frac{ 5 }{ 3 }}$$

anonymous · Answer

$$3x ^{2}=5 $$
$$x ^{2}= \frac{ 5 }{ 3 }$$
$$x = +- \sqrt{\frac{ 5 }{ 3 }}$$
