Question

If the product of zeroes of x2-3kx+ 2K2 -1 is 7, then values of k are ___ and ___.

Answer 1

Answer:

If the product of zeroes of x2-3kx+ 2K2 -1 is 7

So,

A*B = c/a

$(2 {k}^{2} - 1) = 7 \\ 2 {k}^{2} = 8 \\ {k}^{2} = 4$

So,

k = 2 or k = - 2

Answer 2

Answer:

If the product of zeroes of x2-3kx+ 2K2 -1 is 7

So,

A*B = c/a

So,

k = 2 or k = - 2
