Question

if alpha and beta are the zeros of the polynomial x square - 4 x + 1 then find one by Alpha Plus One by beta minus alpha beta

Answer 1

Answer:

-5

Step-by-Step Explanation:

a = 1 , b = 4 and c = 1

Alpha + Beta = -b/a = -4/1 = -4

Alpha*Beta = c/a = 1/1 = 1

Find ,

= alpha + beta - alpha*beta

= -4 - 1

= -5

Answer 2

If alpha and beta are the zeros of polynomial x square - 5 x + 4 what is the value of x minus plus beta -1
