Question

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

Answer 1

Answer

Given expression,

$(81x^2-25)\times \dfrac{6}{18x+10}$

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

Simplifying the given expression

$((9x)^2-5^2)\times \dfrac{3}{9x+5}$

$(9x-5)(9x+5)\times \dfrac{3}{9x+5}$

$3(9x-5)$

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