Question

PLEASE HELP

Given f(x) = x^2 – 5x + k, and the remainder when f(x) is
divided by x - 7 is 34, then what is the value of k?

Answer 1

>> Answer

__________

`\:`

f(x) = x² - 5x + k

f(7) = 34

Soo :

f(7) = 34

(7)² - 5(7) + k = 34

49 - 35 + k = 34

14 + k = 34

k = 34 - 14

k = 20✔

Answer 2

Explanation:

f(7) = 34

7² -5(7) +k = 34

49-35+k =34

14+k = 34

k = 34-14

k = 20
