Question

if one zero of x2+4kx-25 is negative of other .find k

Answer 1

-25/16 may be it is right

Answer 2

Here is your answer by Sujeet,
Given that's polynomial,
x²+4kx-25

Let to be x zeroes of polynomial x²+4kx-25

then,
A/q
x=-x

Again,
a+b=-b/a
x-x=-4kx/x
0=-4k
k=0/-4
k=0



that's all....

I'm right or not...
