If one zero of a quadratic polynomial p(x) =4x2-8kx-9 is negative of the other , find value of k

If one zero of a quadratic polynomial p(x) =4x2-8kx-9 is negative of t

1.	If one zero of a quadratic polynomial p(x) =4x2-8kx-9 is negative of the other , find value of k
Answer» Let\xa0α and\xa0β be the zeros of the polynomial 4x²-8kx-9It is given that\xa0α=-βThen,\xa0α+β=0-b/a=0-(coefficient of x)/coefficient of x²=08k/4=02k=0k=0
