Answer: -16

Explanation:

For x=3 and y=4,

we can write the given expression:
(x+y)/(x-y) -x^(2) as,


((3+4))/((3-4)) -3^(2)


(7)/(-1) - 3^(2)


(-7) - 9

= -16

To evaluate the algebraic expression \(\frac{x+y}{x-y}-x^{2}\) for \(x=3\) and \(y=4\), we substitute the values of \(x\) and \(y\) into the expression.

First, let's substitute the values:

\(\frac{3+4}{3-4}-3^{2}\)

Simplifying the expression further, we have:

\(\frac{7}{-1}-9\)

Dividing 7 by -1, we get:

\(-7-9\)

Combining like terms, we have:

\(-16\)

Therefore, when \(x=3\) and \(y=4\), the expression \(\frac{x+y}{x-y}-x^{2}\) evaluates to \(-16\).
