Question

if one zero of the quadratic polynomial 4 x square +( 2 k + 1 ) x - 9 is negative of other find the value of k​

Answer 1

here is the answer

Let α and β be the zeros of the polynomial 4x²-8kx-9

It is given that α=-β

Then, α+β=0

-b/a=0

-(coefficient of x)/coefficient of x²=0

8k/4=0

2k=0

k=0

4.6
