# Thread: making demoninators the same

1. ## making demoninators the same

With algebraic fractions using different denomonators say

x + 6 - 3 = 0
x x -4

Could somebody please advise the correct method used to make both the denominators the same?

Thanks

David

$\frac{x+6}{x} - \frac{3}{x-4} = 0$

$\frac{(x-4)(x+6)}{x(x-4)} - \frac{3x}{x(x-4)} = 0$

do yourself a favor and learn how to format equations and expressions using Latex ...
