PLEASE HELP

Which x value would make the following expression undefined? *
(81x^2 – 25) * 6/18x + 10

Answer 1

Given expression,

`(81x^2-25)* (6)/(18x+10)`

We have to find the value of x for which the expression is undefined.

Simplifying the given expression

`((9x)^2-5^2)* (3)/(9x+5)`

`(9x-5)(9x+5)* (3)/(9x+5)`

`3(9x-5)`

On solving we can see that the expression is defined for all value of x.
