5. Hasil kali dari (9-4p)(3p-2) adalah…

Jawaban:

-18 + 35p – 12p^2

Penjelasan dengan langkah-langkah:

9 x -2= -18

9 x 3p = 27p

-4p x -2 = 8p

-4p x 3p = -12p^2

Jadi, -18 + 27p + 8p – 12p^2

= -18 + 35p – 12p^2

Penjelasan dengan langkah-langkah:

(9-4p)(3p-2) = 9 x 3p – 9 x 2 – 4p x 3p – 4p x (-2)

= 27p – 18 – 12p^2 + 8p

= 35p – 18 – 12p^2

= -12p^2 + 35p – 18 ✔
