Question

Q 8. Find the value of k ,if sum of zero's is equal to product of zero's of the quadratic polynomial given below
2x2+kx+5​

Answer 1

Answer:

Step-by-step explanation:given,

quadratic equation = 2x^2+kx+5

sum of zeroes = -b/a

product of zeroes = c/a

-k/2=5/2

so k = -5

Answer 2

Answer:

-5

Step-by-step explanation:

quadratic equation=2x^2+kx+5

Sum of zeroes =-b/a

Product of zeroes = c/a

-k/2=5/2

So k= -5
