Question

find the cube polynomial if the zeroes of polynomial are 3,4 & (-2)​

Answer 1

Let us say , a=2,b=−3 and c=4

Putting the values of a, b and c in equation (1) we get :

=x

3

−(2−3+4)x

2

+(−6−12+8)x−(−24)

=x

3

−3x

2

−10x+24

which is required polynomial

Answer 2

Answer:

Here's your answer

x3 – (a + b + c) x2 + (ab + bc + ca)x – abc …(1) To Find: Cubic polynomial whose zeroes are 2, -3 and 4 Let us say, a = 2, b = – 3 and c = 4 Putting the values of a, b and c in the equation (1) we get: = x3 – (2 – 3 + 4) x2 + (-6 – 12 + 8) x – (- 24) = x3 – 3x2 – 10x + 24.
