SOLUTION: If f(x)=x^(3)+10x^(2) & g(x)=9x^(2)-10 f/g is undefined at two points A&B where A<B What is A? What is B? This combination of functions problem has me stuck plz help.

Question 435937: If f(x)=x^(3)+10x^(2) & g(x)=9x^(2)-10
f/g is undefined at two points A&B where A What is A? What is B?
This combination of functions problem has me stuck plz help.

If and , then
, 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.
=> => 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.
