The zeroes of given quadratic polynomial are:

A) \[2,-4\]

B) \[-2,4\]

C) \[3,-4\]

D) \[-3,4\]

Correct Answer: B

Solution :

[b] The zeroes of the quadratic polynomial y \[y=-8-2x+{{x}^{2}}\]are x-coordinates of the points where the graph of y intersects the X-axis.

From the graph \[-2\] and 4 are the x-coordinates of the points where the graph of \[y=-8-2x+{{x}^{2}}\] intersects the X-axis.

Hence, \[-2\] and 4 are zeroes of \[y=-8-2x+{{x}^{2}}.\]

So, option [b] is correct.
