Question

if alpha and beta are the zeros of the quadratic polynomial f x is equal to x square - 5 x + 4 find the value of one by Alpha minus one by beta​

Answer 1

Answer:

by middle split term

x²-5x+4

x²-4x-x+4

x(x-4)-1(x-4)

we get (x-4) and (x-1)

alpha = 4 and beta = 1

according to question alpha - beta

4-1 = 3 answer
