Answer 2

Answer:

option (a)

– 3

Note:

If A and B are the zeros of the quadratic polynomial ax² + bx + c , Then ;

Sum of zeros , (A+B) = -b/a

Product of zeros (A•B) = c/a

Solution:

Here,

The given quadratic polynomial is:

2 - 3x - x² .

The given quadratic polynomial can be rewritten as ; –x² – 3x + 2

Clearly,

Here we have ;

a = -1

b = -3

c = 2

Now,

Sum of zeros of the given quadratic polynomial will be equal to -b/a.

Thus,

Sum of zeros = -b/a = -(-3)/(-1) = -3

Hence,

The required answer is – 3 .

Moreover,

Product of zeros = c/a = 2/(-1) = -2
