Question

determine the excluded value(s) of the rational expression: $f(x)=\frac{-3x + 2}{x^{2}-7x + 6}$. if there are multiple answers, separate them with a comma.

Explanation:

Step1: Set denominator equal to 0

$x^{2}-7x + 6=0$

Step2: Factor the quadratic equation

$(x - 6)(x - 1)=0$

Step3: Solve for x using zero - product property

If $x-6 = 0$, then $x=6$; if $x - 1=0$, then $x = 1$

Answer:

$1,6$
