Question

what is the zeroes of polynomial 4msqaure +8m8m
​

Answer 1

Answer:

helo

Step-by-step explanation:

The question says one root is negative of others.

So, the sum of the roots must be zero.

For any quadratic equation

Like : ax2+bx+c=0

The sum of roots is given by a−b

So, in this equation : 4x2−8ka−9

b=−8k & a=4

So, 0=a−b

4−(−8k)=0

2k=0⇒k=0
