Question

Help! I need to find a solution to the below equation, will give 15 points!
x^2*y-y^2=105

Answer 1

Answer: The correct answer is x = SQRT((y^2+105)/y) OR -SQRT((y^2+105)/y)

Explanation:

x^2*y-y^2=105

Add y^2 to both sides:

x^2y - y^2 + y^2 = 105 + y^2

x^2y = y^2 + 105

Divide both by y:

(x^2y/y) = ((y^2+105)/y)

x^2 = (y^2 +105)/y

x = SQRT((y^2+105)/y) OR -SQRT((y^2+105)/y)
