Find the value for the variable that makes the expression undifined.<br> X2 -9<br> X2-7x+10

Anika [276]

an equation is undefined, when its denominator is 0, or turns to 0, because we can't divide anything by 0.

so let's simply set the denominator of this one = 0.

$\bf x^2-7x+10=0\implies (x-2)(x-5)=0\implies x= \begin{cases} 2\\ 5 \end{cases} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{(2)^2-9}{(2)^2-7(2)+10}\implies \cfrac{-5}{-10+10}\implies \cfrac{-5}{0}\leftarrow und efined \\\\\\ \cfrac{(5)^2-9}{(5)^2-7(5)+10}\implies \cfrac{16}{-10+10}\implies \cfrac{16}{0}\leftarrow und efined$

How do i solve this?

Answer:

Step-by-step explanation:

so first you take the 2 to the 1/4 power and put it in a radical expression so now it is the fourth root of 2 $\sqrt{2}$ but with a little four just like the expression at the end now you still have the 3 power left but $2^{3}$ is 8
