Bài 1:Giải Phương trình
d) \(\frac{3}{2x-16}+\frac{3x-20}{x-8}+\frac{1}{8}=\frac{13x-102}{3x-24}\)
e)\(\frac{6}{x^{2^{ }}-1}+5=\frac{8x-1}{4x+4}-\frac{12x-1}{4-4x}\)
g) \(\frac{\frac{x+1}{x-1}-\frac{x-1}{x+1}}{1+\frac{x+1}{x-1}}=\frac{1}{2}\)
h) \(\frac{x+4}{x^2-3x+2}-\frac{x+1}{x^2-4x+3}=\frac{2x+5}{x^2-4x+3}\)
\(\frac{4}{-25x^2+20x-3}=\frac{3}{5x-1}-\frac{2}{5x-3}\)
\(\frac{1}{x^2-3x+2}+\frac{1}{x^2-5x+6}-\frac{2}{x^2-4x+3}=0\)
\(\frac{x-1}{2x^2-4x}-\frac{7}{8x}=\frac{5-x}{4x^2-8x}-\frac{1}{8x-16}\)
\(\frac{1}{x^2+9x+20}+\frac{1}{x^2+11x+30}+\frac{1}{x^2+13x+42}=\frac{1}{18}\)
Giái cac phương trình sau :
a,\(\frac{1}{x-1}+\frac{2}{x^2+x+1}=\frac{3x^2}{x^2-1}\)
b,\(\frac{10}{3}-\frac{7x+2}{6x+8}=2+\frac{3x+1}{4x+!2}\)
c,\(\frac{2}{x-3}-\frac{27}{x^3-27}=\frac{3}{x^2+3x+9}\)
Giải phương trình:
\(\frac{1}{x^2-3x+2}+\frac{1}{x^2-5x+6}-\frac{3}{x^2-4x+3}=0\)
1) Giải các pt chứa ẩn ở mẫu:
a) \(\frac{x-9}{x}-\frac{x}{x-9}=0\)
b) \(\frac{x+3}{x-2}=\frac{5}{\left(x-2\right)\left(3-x\right)}\)
c) \(\frac{x}{3x-2}-\frac{x}{4x-3}=\frac{x^3}{\left(3x-2\right)\left(4x-3\right)}\)
d) \(\frac{x}{x-5}-\frac{x-5}{x}=0\)
1, giải pt sau
a,\(\frac{9}{x}+2=-6\)
b,\(\frac{7}{x+1}+\frac{-18x}{x\left(x^2+4x+3\right)}=\frac{-4}{x+3}\)
c,\(\frac{3x-1}{x-1}-1=\frac{2x+5}{x+3}+\frac{4}{x^2+2x-3}\)
\(\frac{x}{3x-2}-\frac{4}{4x-3}=\frac{x^2}{\left(3x-2\right)\left(4x-3\right)}\)
\(\frac{x}{3x-2}-\frac{4}{4x-3}=\frac{x^2}{\left(3x-2\right)\left(4x-3\right)}\)
help meeeeeee!!!!!!
giải phương trình :
a) 3x(x-1)=(x-1)(x+2)
b) \(\frac{4x+3}{5}-\frac{6x-2}{7}=\frac{5x+4}{3}+3\)
c) \(\frac{1}{2}\left(x+1\right)+\frac{1}{4}\left(x+3\right)=3-\frac{1}{2}\left(x+2\right)\)
d) ** \(\frac{x+2}{98}+\frac{x+4}{96}=\frac{x+6}{94}+\frac{x+8}{92}\) ưu tiên câu d nha
