Question

Q 7) The product of the zeros of Quadratic polynomial (3k +2)x²+2x + 2 is 1/5 , then the value of k will be​

Answer 1

Answer:

8/3

Step-by-step explain

By using quadratic formula we know that this equation will have two roots.

As we know , α*β=c/a

Now this equation equals-->

(3k +2)x²+2x + 2 =ax^2+bx+c

If we compare the co-efficients, we get that a=3k+2

                                                                         b=2

                                                                         c=2

c/a=1/5=2/3k+2

         By comparing we know that 3k+2=10

                    Therefore, k=8/3
