Question

Find the vertical

Answer 1

when the denominator equals zero

Answer 2

So it would be A?

Answer 3

not quite

how would you factor x^2 - 11x + 24 = 0 ?

Answer 4

You know that A is not correct by checking what you get for the denominator when you substitute the values of \(x\):

\[x^2-11x+24\]\[8^2-11(8)+24 =64-88+24=0\]\(x=8\) is good, as the denominator is \(0\) there

\[(-3)^2-11(-3)+24 = 9+33+24=66\]\(x=-3\) is not good because the denominator does not equal \(0\) there.
