Find the largest possible value of x in the simplified form x= (a + b square root c)/d if , 5x/6 +1 = 3/x, where a,b,c, and d are integers. What is acd/b?
By the quadratic formula, $x = \frac{-4 \pm 4 \sqrt{13}}{7}$, so $\frac{acd}{b} = \frac{(-4)(13)(7)}{4} = -91$.
The answer is 5 when x=3, y =-2
the answer is 5
