Question

Hasil (t - 2)² - (t - 2) - 12 =

Answer 1

Hasil faktornya:
(t - 2 - 4)(t - 2 + 3)
= (t - 6)(t + 1)

atau jika dijabarkan:
t² - 4t + 4 - t + 2 - 12
= t² - 5t - 6

Answer 2

(t - 2)² - (t - 2) - 12
(t - 2)(t - 2) - (t - 2) - 12
(t² - 2t - 2t + 4) - (t - 2) - 12
t² - 4t + 4 - t + 2 - 12
t² - 4t - t + 4 + 2 - 12
t² - 5t + 6 - 12
t² - 5t - 6

Faktornya
(t - 6)(t + 1)
