Question

if α andβare-the-zeroes-of-the-polynomial 2x2-3x-5-find-the-value-of α - β​

Answer 1

Answer:

Step-by-step explanation:

2x^2 - 3x - 5 = 0

2x^2 + 2x - 5x - 5 = 0

2x(x + 1) - 5(x + 1) = 0

(x + 1)(2x - 5) = 0

x = - 1 and x = 5/2

alpha - beta = - 1 - 5/2

= -7/2

Answer 2

Answer:

hope it help u

mark as brain list

alpha -beta = -1-5/2

=-7/2
