Question

Expand the following 2/9(9/4x-9)

Answer 1

2 / 9 x (9 / 4 x - 9) = ?
/ means divide

Answer 2

`(8\cdot x)/(81 - 324\cdot x)`

Explanation:

The expression is:

`(2)/(9\cdot ((9)/(4\cdot x)-9))`

`(2)/(9\cdot ((9-36\cdot x)/(4\cdot x) ))`

`(2)/(9)\cdot (4\cdot x)/(9-36\cdot x)`

`(8\cdot x)/(81 - 324\cdot x)`
