If alpha & beta are zeroes of the quadratic polynomial x2 - 6x + 8, then find the value of alpha - beta (alpha > beta)
please explain the answer step by step
First finding the value of alpha and beta......
x2 - 6x + 8
x2 - 4x - 2x + 8
x(x - 4) -2(x - 4)
(x - 4)(x - 2)
So, therefore alpha = 4 and beta = 2 (as alpha > beta )
Hence, alpha - beta
= 4 - 2
= 2

x2 - 6x + 8
x2 - 4x - 2x + 8
x(x - 4) -2(x - 4)
(x - 4)(x - 2)
So, therefore alpha = 4 and beta = 2 (as alpha > beta )
Hence, alpha - beta
= 4 - 2
= 2
