giải phương trình hộ minh nha mấy bạn <3
a) \(\frac{3x-1}{x-1}-\frac{2x+5}{3}+\frac{4}{x^2-2x-3}=1\)
b) \(\frac{5}{x^2+x-6}+\frac{2}{x^2+4x+3}=\frac{-3}{2x-1}\)
c) \(\frac{4x^2+16}{x^2+16}=\frac{3}{x^2+1}+\frac{5}{x^2+3}+\frac{7}{x^2+5}\)
\(\frac{2}{x+2}-\frac{2x^2+16}{x^3+8}=\frac{5}{x^2-2x+4}\)
\(\frac{1}{x-2}-\frac{6}{x+3}=\frac{5}{6-x^2-x}\)
\(\frac{8}{x-8}+\frac{11}{x-11}=\frac{9}{x-9}+\frac{10}{x-10}\)
Giải các phương trình:
\(a,\frac{2x+1}{x^2-5x+4}+\frac{5}{x-1}=\frac{2}{x-4}\)
\(b,\frac{7}{8x}-\frac{x-5}{4x^2-8x}=\frac{x-1}{2x\left(x-2\right)}+\frac{1}{8x-16}\)
a ) \(\frac{x+5}{x^2-5x}\)- \(\frac{x-5}{2x^2+10x}\)= \(\frac{x+25}{2x^2-50}\)
b ) \(\frac{1}{x-1}-\frac{3x^2}{x^3-1}=\frac{2x}{x^2+x+1}\)
c ) \(\frac{7}{8x}+\frac{5-x}{4x^2-8x}-\frac{x-1}{2x\left(x-2\right)}+\frac{1}{8x-16}\)
Giải phương trình chứa ẩn ở mẫu
a) \(\frac{1}{x^2-2x+2}+\frac{2}{x^2-2x+3}=\frac{6}{x^2-2x+4}\)
b) \(\frac{3x}{x^2+x+1}+\frac{8x}{x^2+2x+1}+\frac{x}{x^2+3x+1}=\frac{16}{5}\)
\(\frac{x+5}{x^2-5x}-\frac{x+25}{2x^2-50}=\frac{x-5}{2x^2+10x}\) \(\frac{x+1}{x-1}-\frac{x-1}{x+1}=\frac{16}{x^2-1}\)
\(\frac{x-1}{12}+\frac{2x-12}{14}=\frac{3x-14}{25}+\frac{4x-29}{27}\)\(\frac{3}{x+1}+\frac{4}{x-2}=/frac{5}{x-3}+\frac{6}{x-4}\)\(\frac{2x-1}{2}+\frac{2x+1}{3}=/frac{2x+7}{6}+\frac{2x+9}{7}\)
