Question

The quadratic polynomial whose sum of zeroes is 3 and product of zeroes is –2 is :
(a) x2 + 3x – 2
(b) x2 – 2x + 3
(c) x2 – 3x + 2
(d) x2 – 3x – 2

Answer 1

Answer:

d

Explanation:

sum of zeroes = -b/a

product of zeroes =c/a

Answer 2

Answer:

x² - 3x - 2

Explanation:

Let ax² + bx + c,

α + β = -b/a

α × β = c/a

3 =  -b/a

-2 = c/a

If a = 1, b = -3 and c = -2

So, x² - 3x - 2
