Question

The sum and product of whose zeros are -3 and 12

Answer 1

Answer:

Step-by-step explanation:

X²+SX+P

X²-3x+12

Answer 2

Solution :

Let m , n are two zeroes of

quadratic polynomial.

m = - 3 , n = 12

m + n = -3 + 12 = 9

mn = (-3)(12 ) = -36

Required polynomial,

k[x² - (m+n)x + mn

= k[x² - 9x -36 ]

For all values of k , it is true

If k = 1 ,

Then polynomial is

x² - 9x -36
