Question

Write the zeros of the polynomial X square + 2 X + 1 also verify the relation alpha + beta equal to minus be divided by a rare alpha and beta are its zeros

Answer 1

${x}^{2} + 2x + 1 = {(x + 1)}^{2}$
(x+1)^2=0
x=-1,-1
α=-1,,,,β-1
α+β=-2...............(1)
b=2,a=1
-b/a=-2/1=-2............(2)
Therefore provef
