Question

(x) {x | x is a prime number}​

Answer 1

alpha and beta are the zeros of the polynomial p(x)=x2-5x+2.

x² - 5x + 2

Sum of Zeroes = -b/a

Products of Zeroes = c/a

a = 1 b = -5 c = 2

Zeroes are a & ß

a +3=5

αβ = 21/a + 1/3

= (B + a)/aß

= 5/2

1/αβ = 1/2

x² - 5x/2 + 1/2 = 0

=> 2x² - 5x+1=0 where zeroes are 1/a & 1/3

1/a & 1/B = (5 ± √25 - 8)/4

=

(5± √17)/4

3aß =3*2= 6

Answer 2

no its not a prime number..
