SOLUTION: solve for all values of x: x-1/x-5

SOLUTION: solve for all values of x: x-1/x-5 - 1/5= 20/x^2-5x

Question 950246: solve for all values of x: x-1/x-5 - 1/5= 20/x^2-5x

Assume the equation is:

Factor out x

multiply by the common denominator 5x(x-5)
5x(x-5)* - 5x(x-5)* = 5x(x-5)*
cancel the denomonators
5x(x-1) - x(x-5) = 5(20)
5x^2 - 5x - x^2 + 5x = 100
Combine like terms
5x^2 - x^2 - 5x + 5x = 100
4x^2 = 100
x^2 = 100/4
x^2 = 25
x = +/-
x = 5
or
x =-5
:
x = 5 cannot be a solution, we would have division by 0 in the original problem
however
x = -5 seems to work ok in the original problem, only solution
