Siapa yg tau gimana caranya

Jawaban:

1) x² + 5x – 14

2) 6x² – 16x +8

Penjelasan dengan langkah-langkah:

(x – 2) (x + 7)

$(x - 2) times (x + 7) \ = x times x + 7x - 2x - 2 times 7 \ = {x}^{2} + 7x - 2x - 14 \ = {x}^{2} + 5x - 14$

(3x – 2) (2x – 4)

$(3x - 2) times (2x - 4) \ = 3x times 2x - 3x times 4 - 2 times 2x - 2 times ( - 4) \ = 6x {}^{2} - 12x - 4x + 8 \ = {6x}^{2} - 16x + 8$

Semoga membantu
