Find the equation for a hyperbola centered at (0, 0), with foci at (-sqrt34, 0) and (sqrt34, 0) and vertices at (3, 0) and (-3, 0).

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
