Question

find the quadratic polynomial the sum and product whose zeroes are -l and -20 respectively . hence find zeroes
​

Answer 1

Step-by-step explanation:

Let Alpha= -1 , Beta= -20.

x^2-(Alpha+ Beta)x + Alpha×Beta

Substitute Alpha = -1 And Beta = -20.

x^2- (-1+(-20))x + -1×-20.

x^2-(-21)x +20

x^2 +21x + 20.

• The Required Quadratic Polynomial is

x^2+21x+20.
