Question

if one root of quaratic equation p²-30+k=0 is 5,then the value of k is.​

Answer 1

Answer:

k = 5

Step-by-step explanation:

p²-30+k=0                                      [ where p = 5]

5² - 30 + k = 0

25 - 30 + k = 0

-5 + k = 0

k = 5

hope this helps you dear..

Answer 2

p2 - 30 + k = 0

(5)^2 -30 +k =0

25-30+k=0

(-5) +k = 0

k = 5
