b) \(\frac{2}{x^3-x^2-x+1}=\frac{3}{1-x^2}-\frac{1}{x+1}\)
a) \(\frac{7x-3}{x-1}=\frac{2}{3}\)
b) \(\frac{1}{x-2}+3=\frac{3-x}{x-2}\)
c) \(\frac{8-x}{x-7}-8=\frac{1}{x-7}\)
d) \(\frac{x+5}{x-5}-\frac{x-5}{x+5}=\frac{20}{x^2-25}\)
e) \(\frac{x}{2\left(x-3\right)}+\frac{x}{2\left(x+1\right)}=\frac{2x}{\left(x+1\right)\left(x-3\right)}\)
f) \(\frac{1}{x}+\frac{1}{x+10}=\frac{1}{12}\)
Mong mọi người giúp đỡ >~~< >__<
1, giải các pt sau
a, \(\frac{7x-3}{x-1}=\frac{3}{2}\)
b, \(\frac{2\left(3-7x\right)}{1+x}=\frac{1}{2}\)
c, \(\frac{1}{x-2}+3=\frac{3-x}{x-2}\)
d, \(\frac{x+5}{x-5}-\frac{x-5}{x+5}=\) \(\frac{20}{x^2-25}\)
giúp mik v mn ơi
\(\frac{3}{4\left(x-5\right)}+\frac{15}{50-2x^2}=\frac{7}{6\left(x+5\right)}\)
Giải các phương trình sau :
1, \(\frac{2x-1}{x^3+1}=\frac{2}{x^2-x+1}-\frac{1}{x-1}\)
2, \(\frac{x+5}{x^2-5x}-\frac{x-5}{2x^2+10x}=\frac{x+25}{2x^2-50}\)
Giups mk với các bạn mk cần gấp . Mk cảm ơn :)))
1. Giải phương trình
a) \(\frac{2}{x^2-x-6}+\frac{x+1}{x^2+x-12}=\frac{x}{x^2+6x+8}\)
b) \(\frac{2x-5}{x^2+5x-36}-\frac{x-6}{x^2+3x-28}=\frac{x+8}{x^2+16x+63}\)
c) \(\frac{x-2}{4x^2-29x+30}-\frac{x+1}{20x^2-13x-15}=\frac{x+2}{5x^2-274x+18}\)
\(\frac{x+5}{x^2-5x}\)-\(\frac{x+25}{2x^2-50}\)=\(\frac{x-5}{2x^2+10x}\)
Mn giúp em câu này nha.
