Question

Simplifique as frações algébricas. Ajudem, por favor

Answer 1

A) $\frac{x^{3}+3x^{2}+3xy^{2}+y^{3}-x^{3}-x^{3}}{3}\\\frac{3(x^{2}y+xy^{2})}{3}\\x^{2}y+xy^{2}$

B) Não consegui. :(

C) $\frac{(x+1)^{2}}{x*(x+1)}\\\frac{x+1}{x}$

D) $\frac{x^{2}-2x-3x+6}{x^{2}-2x-5x+10}\\\frac{x*(x-2)-3(x-2)}{x*(x-2)-5(x-2)}\\\frac{(x-2)*(x-3)}{(x-2)*(x-5)}\\\frac{x-3}{x-5}$

F) $\frac{4(x^{2}+2bx+b^{2})*(x-b)}{2(x^{2}-b^{2}*(-(x+b))}\\\frac{x(x+b)}{-(x+b)}\\2*(-1)\\-2$
