Question

If alpha and beta are the zeros of quadratic polynomial 2ysquare + 7y + 5


FIND THE VALUE OF ALPHA + BETA AND ALPHA × BETA

Answer 1

alpha + beta = -7/2

alpha.beta = 5/2

Answer 2

Answer: (-7/2) and (5/2)

Step-by-step explanation:

EQUATION =2x²+7x+5

(a=2, b=7, c=5)

By using relation of coefficient with zeroes

(alpha+beta) = (- b/a) = (-7/2)

(Alpha×beta) = (c/a) = (5/2)
