# Math Help - Solving unknown values.

1. ## Solving unknown values.

Pls help with this question.

A hyperbola with equation y^2 + Ay +Bx^2 + Cx + D = 0, where A,B, C and D are real constants, passes through the point (5/3, 17) and has a maximum point ( -1, 1 ). Find A, B and C.

2. ## Re: Solving unknown values.

What have you tried? Where are you stuck?

You can substitute the given points into the equation, which gives you two equations for the four unknowns, but as D can be eliminated, I would probably then just differentiate and substitute in the maximum point's coordinates to get the third equation.

Please show your work because this is a lengthy question and it would be beneficial for everyone involved if we could pinpoint the exact difficulty.
