Question

Find the value of k, if (x-1) is a factor of 2x1-9x2+3x+k?



please I have exam now please answer fast​

Answer 1

Answer:

13

Step-by-step explanation:

p(x) = 2x1 - 9 x2 + 3x + k

p(1) = 2-18 + 3 +k

p(1) = - 13 + k

          k= 13

Answer 2

P(x) = 2x - 9x² + 3x + k
If x = 1

P(x) = 2(1) - 9(1)² + 3(1) + k
P(x) = 2 - 9 + 3 + k
P(x) = 5 - 9 + k
P(x) = - 4 + k

-4 + k = 0
K = 4
