Ubah ke bentuk umum persamaan kuadrat : (X + 1)(x + 2)(x + 3) - (x + 4)(x + 5)(x + 6) = 0

Jawab:

(x^3 + 6x^2 + 11x + 6) - (x^3 + 15x​​^2 +74x+120) = 0

Terima kasih

(x+1)(x+2)(x+3) = (x+4)(x+5)(x+6)
(X^2 + 3x + 2 )(x+3) = (X^2 + 9x + 20) (x+6)
X^3 + 3X^2 + 2x + 3x^2 + 9x + 6 = X^3 + 9X^2 + 20x + 6x^2 +54x +120
6x^2 + 11x + 6 = 15x^2 + 74x +120
9x^2 + 63x + 114 = 0
3x^2 + 21x +38 = 0

semoga bermamfaat yaa ;;)
