What are the domain restrictions of the expression h23h10h212h20 Select each correct answer h5h2h2h10h5h10 class=

Respuesta :

We have the expression:

[tex]\frac{h^2+3h-10}{h^2-12h+20}[/tex]

To determine the restrictions we factor the quadratic function in the denominator (Since is the only one that is capable of making the expression not make sense):

*What we will be looking are the values that make that function zero:

[tex]h^2-12h+20=(h-10)(h-2)[/tex]

From this, we can see that the values that present a restriction (The values that will make the denominator zero) are:

h = 10 & h = 2.

So, the two answers are h = 10 & h = 2.
