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:

(a)

Step-by-step explanation:

sum of zeroes =3

then, alpha +beta = -b/a

product of zeroes, =-2

then, alpha ×beta = c/a

-b/a = -3/1

c/a = -2/1

therefore,

x2+3x-2 is the required polynomial
