Question

$text If end text a x to the power of 2 end exponent plus 2 h x y plus b y to the power of 2 end exponent plus 2 g x plus 2 f y plus c equals 0$ represents a pair of parallel lines then $square root of fraction numerator g to the power of 2 end exponent minus a c over denominator f to the power of 2 end exponent minus b c end fraction end root equals$

$\frac{a}{b}$
$\sqrt{\frac{a}{b}}$
$\sqrt{\frac{b}{a}}$
$\frac{b}{a}$

The correct answer is: $square root of fraction numerator a over denominator b end fraction end root$

$2 square root of fraction numerator g to the power of 2 end exponent minus a c over denominator a left parenthesis a plus b right parenthesis end fraction end root equals 2 square root of fraction numerator f to the power of 2 end exponent minus b c over denominator b left parenthesis a plus b right parenthesis end fraction end root$
