Question

-2 and -1 quadratic polynomial if the zeroes are given

Answer 1

Step-by-step explanation:

is -2 and-1 are zeroes ¹of the polynomial

sum of zeroes= -3

product of zeroes =+2

required equation= using formula

x²-(a+b)x+ab=0

equation= x²-(-3)x+2=0

= > x²+3x+2=0

Answer 2

Answer:

let αandβ be the zero of the polynomial

α+β = -b/a

-2+(-1) = -3

αβ= -2×-1

= 2

so the polynomial is

x²-(α+β)x +αβ

x²-(-3)x+2

x²+3x+2
