Question

find the zeros of the quadratic polynomial 2 y ^2 + 4 Y and verify the relationship between the zeros and their coefficients​

Answer 1

2y² + 4y

y² + 2y

alpha + beta = -2/1 = -2

alpha × beta = 0/1 = 0

alpha - beta = √4 - 0

alpha - beta = 2

alpha + beta = -2

alpha - beta = 2

---------------------------

2alpha = 0

alpha = 0

alpha + beta = -2

0 + beta = -2

beta = -2

Alpha + beta = -b/a

-2 + 0 = -2/1

-2 = -2

Alpha × beta = c/a

-2 × 0 = 0/1

0 = 0
