If one zero of quadratic polynomial 4x²-8kx-9 os negative of the other find the value of k |
Answer» Answer :-→ k = 0 . Step-by-step explanation :-It is GIVEN that, → One zeros of the given polynomial is NEGATIVE of the other . Let one zero of the given polynomial be x . Then, the other zero is -x . •°• Sum of zeros = x + ( - x ) = 0 . But, Sum of zeros = -( COEFFICIENT of x )/( coefficient of x² ) = - ( -8k )/4 . ==> 2k = 0 . ==> k = 0/2 .
Hence, it is SOLVED. |
