Question

29PK tolong yah hehe

Answer 1

Ax^2 + bx + c = 0
x^2 - 6x + 2 = 0
a = 1
b = -6
c = 2

m + n = n + m = -b/a = -(-6)/1 = 6
mn = c/a = 2/1 = 2

x1 = (1/m + 1/n)^(mn)
= ((n + m)/mn)^(mn)
= (6/2)^2
= 3^2 = 9
(x - 9) = 0

x2 = (mn)^(1/m + 1/n)
= (mn)^((n + m)/mn)
= 2^(6/2)
= 2^3 = 8
(x - 8) = 0

(x - 9)(x - 8) = 0
x^2 - 8x - 9x + 72 = 0
x^2 - 17x + 72 = 0 (a)
