Question

Rozwiąż równanie xkwadrat=6x+1

Answer 1

x^2 = 6x + 1

x^2 - 6x - 1 = 0

delta = ( -6)^2 - 4*1*(-1) = 36 + 4 = 40 = 4*10

p (delty) = 2 p(10)

x1 = [ 6 - 2 p(10)]/2 = 3 - p(10)

x2 = [ 6 + 2 p(10)]/2 = 3 + p(10)

==============================

p(10) - pierwiastek kwadratowy z 10

Answer 2

x =
