for which value of x is the expression undefined x+5/2x-5

Question

um..this is pretty much it...

Answer 1

for (x+5)/(2x-5) the expression is undefined when 2x-5 = 0 or when x = 5/2

that makes the denominator =0. Division by zero makes the expression undefined

IF by chance, the expression was x + (5/2x) - 5 then x=0 makes the expression undefined. Odds are though that there were implicit parentheses making the expression (x+5)/(2x-5)
