the point tangent to line
At what point on the curve xy = ( 1 - x - y)^2 is the tangent line parallel to the x - axis
need your assistance here guys...

What is the gradient of the x axis? Hint: It's horizontal...

now find a point
so that
.

If you do not know what "gradient' (American English: "slope") of a line is, you should not be attempting a problem like this. Finding the derivative is far more advanced that the 'slope' or 'gradient' of a line.

You've posted a lot of algebra questions on this forum, and this question might be too advanced for you. How much calculus do you know?

i guess basic for u but im trying to know all these things sir :(

What the hell does that mean?
That is not even a well formed English sentence
If you cannot post an proper statement or question then post nothing !

I don't think you're quite ready for derivatives and calculus, especially since you've been posting elementary algebra questions. You need to be proficient in algebra to do well in calculus.
Re: the point tangent to line
The solution would involve differentiating both sides with respect to x:
(using chain rule)
Then set dy/dx = 0.

thank you Plato. You have a very positive statement :). Keep it up!
