1).

$frac{36 {p}^{4} {q}^{2} {r}^{2} s}{24 {p}^{2} {r}^{2} } div frac{ - 2 {p}^{2} {q}^{2} rs}{(x - 2)} \ = frac{36 {p}^{4 - 2} {q}^{2} {r}^{2 - 2} s }{24 } times frac{(x - 2)}{ - 2 {p}^{2} {q}^{2} rs} \ = frac{3 {p}^{2} {q}^{2} s times ( x - 2)}{24 times - 2 {p}^{2} {q}^{2} rs } \ = frac{3 {p}^{2 - 2} {q}^{2 - 2} {s}^{1 - 1} times (x - 2) }{24 times - 2r} \ = frac{3(x - 2)}{ - 48r} = frac{3x - 6}{ - 48r} = frac{x - 2}{ - 16r}$

2). x³ – 2x² – 5x + 6

Caranya ada di gambar

3). Misalkan:

sendok = s

piring = p

gelas = g

Jadi bentuknya:

(5s + 5p + 5g) – (s + p) + (2p + 3s + g)

= 5s + 5p + 5g – s – p + 2p + 3s + g

= 5s – s + 3s + 5p – p + 2p + 5g + g

= 7s + 6p + 6g

Maka terdapat 7 sendok, 6 piring dan 6 gelas
