Question

p(x)= x2-(5k+8)x-35
where x=7 and find K​

Answer 1

Step-by-step explanation:

the answer will be 49-5k+56-35=0

49-5k+21=0

-5k=-70

k=70/5

k=14

Answer 2

Answer:

k=-6/5

Step-by-step explanation:

p(x)=x^2-(5k+8)x-35

p(7)=7^2-(5k+8)7-35

     =49-35k-56-35

     =49-35k-91

     =-35k-42

35k=-42

k=-42/35

k=-6/5
