Find the equation of a pair of lines passing through the point (1, 0) and parallel to the lines represented by the equation
3x² + xy - 10y^2 = 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.
