Question

Find the sum and product of zeroes of the quadratic polynomial 2x²+3x+7.
​

Answer 1

Answer:

sum = -3/2    product = 7/2

Step-by-step explanation:

let a and b be the zeroes.

Thus ,

P(x) = x^2 - (a+b)x + ab

On comparing we get the above answer

Answer 2

alpha+beta=-b/a

= -3/2

alpha×beta=c/a

=7/2

Therefore, the sum and product of the zeroes of the quadratic polynomial 2x²+3x+7 is -3/2 and 7/2 respectively.
