How do you solve #(x+5)^2 /( x^2-4 )>=0#?
Ans: Open intervals: (-inf, -2) and (2, +inf)
This function is undefined when
Solve this inequality algebraically by using a sign chart.
g(x) < 0 between (-2) and (2).
Sign Chart. of
Sign of F(x) is the resultant sign of f(x) and g(x).
F(x) is positive in interval (-inf, -2) and F(x) > 0 inside (2, +inf).
Ans: Open Intervals: (-inf, -2) and (2, +inf).
