Question

If one of zeroes of quadratic polynomial is (k+2)x^2+kx+4 is -4 find the value of k

Answer 1

Answer:

'k' value is -3.

Step-by-step explanation:

Given,

(k+2)x²+kx+4

=> (k+2)(-4)² + k(-4) + 4

=> (k+2)(16) + k(-4) + 4

=> 16k + 32 - 4k + 4

=> 12k + 36

=> 12k = -36

=> k = -36/12

:. k = -3.
