Question

Упрости выражение 9p+6p−4−p−3p−4+6p+24−p.

Answer 1

Ответ:

$\frac{2p+7}{p-4}$

Объяснение:

$\frac{9p+6}{p-4} -\frac{p-3}{p-4} +\frac{6p+2}{4-p} =\frac{9p+6}{p-4} -\frac{p-3}{p-4} +\frac{6p+2}{-(p-4)} =\frac{9p+6}{p-4} -\frac{p-3}{p-4} -\frac{6p+2}{p-4} =\\\\=\frac{(9p+6)-(p-3)-(6p+2)}{p-4} =\frac{9p+6-p+3-6p-2}{p-4} =\frac{(9p-p-6p)+(6+3-2)}{p-4} =\frac{2p+7}{p-4}$
