Question

what are the restricted value of ratio expressed in fraction

Answer 1

Restricted values are values that will make the denominator equal to 0.

The denominator in the given expression is:

$\text{ x}^2\text{ - 4x}$

Now, let's determine what values should be restricted for the denominator not to be zero.

We get,

$\text{ x}^2\text{ - 4x = 0}$$\text{ x}^2\text{ = }4\text{x}$$\text{ }\frac{\text{x}^2}{\text{ x}}\text{ = }\frac{4\text{x}}{\text{ x}}$$\text{ x = 4}$

Therefore, the restricted value of the given ratio is 4.

Or,

$\text{ x }\ne\text{ 4}$
