Giải phương trình:
1.\(\frac{1}{x^2}\) + \(\frac{1}{\left(x+2\right)^2}\) = \(\frac{3}{4\left(x+1\right)^2}\)
2.8x2 + 10x +3 = \(\frac{1}{4x^2+7x+3}\)
3.(x2 + 6x +10)2 + (x+3)(3x2 +20x +36) = 0
4.\(\frac{1}{\left(2x-1\right)^2}\) + \(\frac{1}{\left(3x+1\right)^2}\) = \(\frac{5}{4\left(x+2\right)^2}\)
5.\(\frac{4x^2}{\left(x+3\right)^2}\) = 3x2 - 6x -8
bấm máy tính casio là ra đc đấy :))
