d, \(\frac{12}{1-9x^2}\) = \(\frac{1-3x}{1+3x}\) - \(\frac{1+3x}{1-3x}\)

e, \(\frac{x+5}{x-1}\) = \(\frac{x+1}{x-3}\) - \(\frac{8}{x^2-4x+3}\)

f,\(\frac{x+1}{x-2}\)- \(\frac{5}{x+2}\) = \(\frac{12}{x^2-4}\) +1

Bài 3:Tìm giá trị nhỏ nhất của biểu thức A=\(^{x^2}\)+ x+2012

Bài 1:Giải phương trình:

a, (3x-2)(4+5x) = 0

b, \(\frac{3x-2}{5}\) - 2x+3 = \(\frac{2x-1}{2}\) - \(\frac{x-3}{10}\)

c, \(\frac{2}{x+1}\) - \(\frac{1}{x-2}\) = \(\frac{3x+5}{\left(x+1\right)\left(x-2\right)}\)

Bài 2: Giải các phương trình sau

a, 5 +\(\frac{96}{x^2-16}\) = \(\frac{2x-1}{x+4}\) - \(\frac{3x-1}{4-x}\)

b, \(\frac{3x+2}{3x-2}\) - \(\frac{6}{2+3x}\) = \(\frac{9x^3}{9x^2-4}\)

c, \(\frac{x+1}{x^2+x+1}\) - \(\frac{x-1}{x^2-x+1}\) = \(\frac{3}{x\left(x^4+x^2+1\right)}\)
