Question

Find the value of k, if x-2 is a factor of p(x) = 2x^2 + k x + 4.​

Answer 1

Answer:

Step-by-step explanation:

X-2=0

X=2

2x^2+kx+4

2×4+k×2+4=0

8+2k+4=0

2k+12=0

2k=-12

K=-12/2

K=-6

Answer 2

Answer:

QUESTION:-

Find the value of k, if x-2 is a factor of p(x) = 2x^2 + k x + 4?

Step-by-step explanation:

SOLUTION:-

x-2=0

x=2

SO,P(x)=P(2)

=> 2×(2)²+k×2+4=0

2×4+2k+4=0

8+2k+4=0

12+2k=0

2k+12=0

2(k+6)=0

k+6=0

k=-6
