#### Explanation:

Solve the equation as you normally would.

Move the

#x^2=3#

Take the square root of both sides. Recall that the square root can be positive or negative.

#sqrt(x^2)=+-sqrt3#

#x=+-sqrt3#

These are the only two roots (both of which are real). We know the equation will only have two roots since the function's degree (largest exponent) is
