Replace every copy of x with 7 \[\Large h(x) = \frac{x^2-11x+24}{x-1}\] \[\Large h(x) = \frac{(x)^2-11(x)+24}{(x)-1}\] \[\Large h({\color{red}{x}}) = \frac{({\color{red}{x}})^2-11({\color{red}{x}})+24}{({\color{red}{x}})-1}\] \[\Large h({\color{red}{7}}) = \frac{({\color{red}{7}})^2-11({\color{red}{7}})+24}{({\color{red}{7}})-1}\] Do you see how to simplify this?

so would it be 49 - 77 + 24 / 6? i wasnt sure if that was the final answer

jimthompson5910 (jim_thompson5910):

what does the numerator 49 - 77 + 24 simplify to?

OpenStudy (angelax0):

-4

jimthompson5910 (jim_thompson5910):

so we have -4/6 which reduces to what?

OpenStudy (angelax0):

-2 / 3?

jimthompson5910 (jim_thompson5910):

yes so -2/3 is the final answer

jimthompson5910 (jim_thompson5910):

you'll enter it as a fraction, not a decimal
