<span>The function is undefined when x = 3.
You have a function where the numerator is 1 and the denominator is an expression with the variable x. That function will be undefined at those points where the denominator has a value of zero. So let's look at just that part of the function and solve it for where its value is zero.
(x-5)^2 + 4(x-5) + 4 = 0
Perform the squaring of (x-5)
x^2 - 10x + 25 + 4(x-5) + 4 = 0
Distribute the 4
x^2 - 10x + 25 + 4x - 20 + 4 = 0
Combine common terms (add -10x to 4x, and add 25 to -20 to 4)
x^2 - 6x + 9 = 0
We now have a quadratic equation with a=1, b = -6, and c=9. Solve using the quadratic formula, giving a root of x = 3.
Verify by seeing if x=3 gives a denominator of 0..
(x-5)^2 + 4(x-5) + 4 = y
(3-5)^2 + 4(3-5) + 4 = y
(-2)^2 + 4(-2) + 4 = y
4 + -8 + 4 = y
0 = y</span>
The answer is 120 dived by 3 is 40
