\(8\left(x+\frac{1}{x}\right)^2+4\left(x^2+\frac{1}{x^2}\right)^2-4\left(x^2+\frac{1}{x^2}\right)\left(x+\frac{1}{x}\right)^2=\left(x+4\right)2\)
giải pt
Giải các pt sau
a,\(\frac{1}{x+2}+\frac{2}{x+3}=\frac{6}{x+4}\)
b,\(\frac{1}{x\left(x+2\right)}+\frac{1}{\left(x+2\right)\left(x+4\right)}+\frac{1}{\left(x+4\right)\left(x+6\right)}\)
c,\(\frac{6x+22}{x+2}-\frac{2x+7}{x+3}=\frac{x+4}{x^2+5x+6}\)
Giải các PT sau:
a/ \(\left(\frac{x}{x+1}\right)^2+\left(\frac{x}{x-1}\right)^2=90\)
b/ \(20\left(\frac{x-2}{x+1}\right)^2-5\left(\frac{x+2}{x-1}\right)+48\left(\frac{x^2-4}{x^2-1}\right)=0\)
Giải PT sau!!
\(20\left(\frac{x-2}{x+1}\right)^2-3\left(\frac{x+2}{x-1}\right)+48.\frac{x^2-4}{x^2-1}=0\)
Giúp với!!
giải các pt sau
\(\frac{x+1}{3}+\frac{3\left(2x+1\right)}{4}=\frac{2x+3\left(x+1\right)}{6}+\frac{7+12x}{12}\)
\(\frac{2\left(3x+1\right)+1}{4}-5=\frac{2\left(3x-1\right)}{5}-\frac{3x+2}{10}\)
\(\frac{3\left(x-3\right)}{4}+\frac{4x-10.5}{10}=\frac{3\left(x+1\right)}{5}+6\)
\(\frac{x+1}{58}+\frac{x+2}{57}=\frac{x+3}{56}+\frac{x+4}{55}\)
giải pt:
\(\left(x^2+\frac{1}{x^2}\right)+3\left(x+\frac{1}{x}\right)+4=0\)
Đang cần gấp. Ai nhanh+đúng 3tiks
Giải các pt sau
\(a,\frac{1}{2}\left(x+1\right)+\frac{1}{4}\left(x+3\right)=3-\frac{1}{3}\left(x+2\right)\)
\(b,\left(2x+1\right)^2=\left(x-1\right)^2\)
\(c,\left(x^2-5\right)\left(x+3\right)=0\)
\(d,\frac{x+5}{3x-6}-\frac{1}{2}=\frac{2x-3}{2x-4}\)
\(e,\frac{1}{x+1}-\frac{5}{x-2}=\frac{15}{\left(x+1\right)\left(2-x\right)}\)
giải pt \(x\left(x-1\right)\left(x+1\right)\left(x+2\right)=24\)
\(\left(x+3\right)^4+\left(x+5\right)^4=2\)
\(\frac{x^2+x+4}{2}+\frac{x^2+x+7}{3}=\frac{x^2+x+13}{5}+\frac{x^2+x+16}{6}\)
\(\frac{x+19}{3}+\frac{x+13}{5}=\frac{x+7}{7}+\frac{x+1}{9}\)
giúp vs mình cần gấp
rút gọn pt
1. A= \(\frac{x}{x-3}-\frac{x^2+3x}{2x+3}\left(\frac{x+3}{x^2-3x}-\frac{x}{x^2-9}\right)\)
2. B= \(\left[\frac{x^2}{x^2-1}-\frac{x^2}{x^2+1}\left(\frac{x}{x+1}+\frac{1}{x^2+x}\right)\right]:\frac{1}{x-1}\)
Giải cụ thể giúp em với ạ, em cảm ơn
