Solve the rational equations.

Solve the rational equations. a. x - 3/x + 5 = 0 b. x - 3/x + 5 lessthanorequalto 0 c. x - 3/x + 5 greaterthanorequalto 0

Solution

A. (x-3)/(x+5)=0

x-3=0

x=3

B.(x-3)/(x+5)<=0

Testing points x-3=0, x+5=0

x=3,-5

x is negative in region -5 to 3

Therefore solution is (-5,3]
