Question

CРОЧНО,ПОЖАЛУЙСТА!!!!!!!!!!!!!!УПРАСТИТЕ ВЫРАЖЕНИЯ:3c+a/4c - a-7c/4c2p/p+3 + 3-p/p+3x^2/x-4 + 4x/4-xm/m^2-n^2 - n/m^2-n^2

Answer 1

$\frac{3c+a}{4c} - \frac{a-7c}{4c} = \frac{10c}{4c} =2.5 \\\\ \frac{2p}{p+3} + \frac{3-p}{p+3} = \frac{p+3}{p+3} =1 \\\\ \frac{x^2}{x-4} + \frac{4x}{4-x} = \frac{x^2}{x-4} - \frac{4x}{x-4} =x \\\\ \frac{m}{m^2-n^2} - \frac{n}{m^2-n^2} = \frac{1}{m+n}$
