write the value or values of the variable that make a denominator 0
To find the value for which denominator becomes 0, equate the denominator of each term to 0.
x + 3 = 0
x = -3
x - 3 = 0
x = 3
x + 3 = 0 or x - 3 = 0
x = -3 or x = 3
ANSWER: For x = 3 and x = -3 the denominator becomes 0 for the given equation.
what value would make the denominator equal to 0...that is the first part of the question and I don't understand... thx
If you put x = 3 in the equation, it becomes
Here denominator of the 4/x-3 term and 2x/x^2-9 terms became 0.
If you put x = -3 in the equation it becomes
Here denominator of the 3/x+3 term and 2x/x^2-9 term became 0.
So, the values which make the denominator 0 are x = 3 and x = -3.
If you have any doubts please do ask.
