What is the largest value of x such that (x + 1)/(7x^2 - 50x + 7) is not defined?
What is the largest value of x such that (x + 1)/(7x^2 - 50x + 7) is not defined?
To be undefined, the denomitor has to equal zero.
Factor 7x2 – 50x + 7 and obtain (7x – 1)(x – 7) then set each factor equal to zero.
7x – 1 = 0 therefore x = 1/7
x – 7 = 0 therefore x = 7
You want the larger value, so your answer is x = 7
