Find all pairs of real numbers such that x + y = 10 and x^2 + y^2 = 56 + xy. For example, to enter the solutions and , you would enter "(2,4),(-3,9)" (without the quotation marks).
The solutions are
$(\frac{\sqrt{93}}{3} + 5, -\frac{\sqrt{93}}{3} + 5)$ $(-\frac{\sqrt{93}}{3} + 5, \frac{\sqrt{93}}{3} + 5)$
