Question

5) The value of K, if x - 2 is a factor of p(x) = kx2 - 3x + k
a) o b) 5/6 c) 6/5 d) -5/6​

Answer 1

Answer :

⇒x - 2 = 0

⇒ x = 2

_____________

⇒kx² - 3x + k = 0

⇒k(2)² - 3(2) + k = 0

⇒k(4) - 6 + k = 0

⇒4k - 6 + k = 0

⇒ 5k - 6 = 0

⇒ 5k = 6

⇒ k = 5/6

➜ Answer is (b) 5/6

Answer 2

Answer:

C-6/5

Step-by-step explanation:

x-2=0

x=2

p(2)=k(2)²-3(2)+k

=4k-6+k

=5k-6

5k-6=0

5k=6

k=6/5
