[From: ] [author: ] [Date: 12-04-29] [Hit: ]
noticing that its a quadratic in xy,xy = ⅕,Is any of that what you were looking for?No solution!-What are you trying to solve?The zeros?......
I need help with this math problem 1-xy-20x^2y^2. How do I solve it? Thank You.

It's an expression, not an equation, or a problem. It isn't subject to being solved.

It can perhaps be factored or simplified. Like, noticing that it's a quadratic in xy, you can go:

1 - xy - 20x²y² = 1 - xy - 20(xy)² = (1 - 5xy)(1 + 4xy)

Or you can look for its zeroes:
1 - xy - 20x²y² = 0
(1 - 5xy)(1 + 4xy) = 0
xy = ⅕, -¼

Is any of that what you were looking for?

-
- (4*x*y + 1)*(5*x*y - 1) = 0

4*x*y = - 1
5*x*y = 1

No solution!

-
What are you trying to solve?
The zeros?

-
Xy=1 and xy=1/20
