Find the largest possible value of x in the simplified form:

x = (a+b√c)/d if (5x)/6+1=3/x,

where a,b,c, and d are integers.

What is (acd)/b?

Here is some playing with your problem!

 

5x^2 + 6x - 18 =0, solve for x
x =~ 1.39
x =~ -2.59
x =a + b*sqrt(c) / d
x =4 + 15*sqrt(81) / 100
x= 4 +15*9 / 100
x= (4 + 135) / 100
x = 139 / 100
x = 1.39
(acd) / b
(4*81*100) / 15 =2,160
