Question 435937
If {{{f(x)=x^3+10x^2}}} and {{{g(x)=9x^2-10}}}, then 

{{{f(x)/g(x)=(x^3+10x^2)/(9x^2-10)}}}, this rational function is undefined for 

 values of x that makes denominator zero. To find these values set denominator to 

zero and solve the equation.

{{{9x^2-10=0}}} => {{{x^2=10/9}}} => x=+/-sqrt(10/9)=> x=+/-sqrt(10)/3.

Answer:The two undefined points are A(-sqrt(10)/3) and B(sqrt(10)/3).
       The points are on the number line.
