Question

Carilah hasil 2 (x+1)^2 dan (x^2+2)^2 -1. Tolong ya kak.

Answer 1

2(x+1)^2 = 2(x+1)(x+1) = 2(x^2 + x + x + 1) = 2(x^2 + 2x + 1) = 2x^2+4x+2

(x^2+2)^2 -1 = (x^2+2)(x^2+2) -1 = (x^4 +2x^2 + 2x^2 +4)-1 = x^2+4x^2+3

semoga tidak salah. semoga membantu

Answer 2

2  = 2 ( + 2x +1)
                                   = 2 + 4x + 2

= 
                                          =
