Cần gấp giúp nhanh hộ mình với ạ !!!!
Giải các phương trình sau:
a) \(\left(x-3\right)\left(1-x\right)=\left(2x-3\right)\left(x+5\right)\)
b) \(\frac{3}{5x-1}+\frac{2}{3-5x}=\frac{4}{\left(1-5x\right)\left(x-3\right)}\)
c) \(\frac{x+1}{x^2+x+1}-\frac{x-1}{x^2-x-1}=\frac{3}{x\left(x^4+x^2+1\right)}\)
d) \(\frac{m-3}{m+3}-\frac{1-3m}{1+3m}-1\)
e)\(\frac{x}{3+x}-\frac{x}{x-3}=\frac{1}{9-x^2}\)
giải các phương trình sau
\(\frac{x+2}{x-2}-\frac{1}{x}=\frac{2}{x^2-2x}\)
\(\frac{2x}{2x-1}+\frac{x}{2x+1}=1+\frac{4}{\left(2x-1\right)\left(2x+1\right)}\)
\(\frac{2x-1}{3}+x=\frac{x+4}{2}\)
\left(1-\frac{x-1}{x+1}\right)\left(x+2\right)=\frac{x+1}{x-1}+\frac{x-1}{x+1}
Giải phương trình:
\(\frac{1}{x-1}-\frac{1}{x+1}=\frac{1}{x-2}+\frac{1}{x+2}\)
Giải pt:
1. x-4=2x+4
2. \(\frac{2x-1}{2}-\frac{x}{3}=x-\frac{x}{6}\)
3.\(\frac{x+3}{2x+1}-\frac{x}{x-3}=\frac{3x^2+x+9}{\left(2x+1\right)\left(x-3\right)}\)
4.\(\frac{2x}{3}+\frac{2x-1}{6}=4-\frac{x}{3}\)
\(\frac{1}{x^2+2x}+\frac{1}{x^2+6x+8}+\frac{1}{x^2+10x+24}+\frac{1}{x^2+14x+48}=\frac{4}{105}\)
Giúp mk vs
