Question

Деление дробей:

9р^2-1рg-2g:1-3р3р-6

Answer 1

$frac{9 {p}^{2} - 1 }{pg - 2g} div frac{1 - 3p}{3p - 6} = frac{9 {p}^{2} - 1}{pg - 2g} times frac{3p - 6}{1 - 3p} = frac{(3p - 1)(3p + 1)}{g(p - 2)} times frac{3(p - 2)}{1 - 3p} = frac{ - (1 - 3p) times (3p + 1) times 3(p - 2)}{g(p - 2) times (1 - 3p)} = frac{ - 3(3p + 1)}{g}$
