Question

if the sum o zero of polynomial p(x)=2x cube-3kxsquare +4x-5 than find the value of k​

Answer 1

Answer:

correct option is

B

4

The sum of the zeroes of the equation ax  

3

+bx  

2

+cx+d is −b/a

Here the equation is 2x  

3

−3kx  

2

+4x−5

⇒ Sum of roots=3k/2

⇒ 3k/2=6

⇒ k=4

Step-by-step explanation:

Answer 2

Step-by-step explanation:

sum is zero means

alpha + beta = -b /a

Then k = 0
