Question

if the product of zeroes of following quadratic polynomial is 2 then value of k is x2+4x+k​

Answer 1

Answer:

k = -1/2

Step-by-step explanation:

Because, it is given that product of zeroes of polynomial is 2 .

In this polynomial it is given that

a = 1

b = 4

c = k

So, alpha+beta = -b/a

= -4/1

= -4

Now, alpha x beta = c/a

= k/1

= k

Now, we need to multiply (-4) and (k) and equate it to 2

i.e. (-4) x k = 2

k = 2/(-4)

k = -1/2

Hope so it helped you......

Answer 2

Answer:

given product of two zeros is 2

then product of zeros in equation =c/a=k/1

Therefore, k=2
