(x - 1)2 - (x + 1)2 = 5 - 6x
<=> x2 - 2x + 1 - x2 - 2x - 1 = 5 - 6x
<=> -4x = 5 - 6x
<=> -4x + 6x = 5
<=> 2x = 5
<=> x = \(\frac{5}{2}\)
(x-1-x-1)(x-1+x+1)=5-6x
-2.2x=5-6x
2x-5=0
x=5/2

Mình cần lẹ mấy bạn giúp ạ
giải các phương trình
a, \(\frac{2}{x-1}+\frac{5}{x+2}=\frac{13}{x^2+x-2}\)
b, \(\frac{2x-1}{x-3}=\frac{6x-1}{3x+2}\)
c, \(|-3x|=x-10\)
d, \(|3x-1|-x+2=0\)
e, \(|x^2-3x+5|=3x+x^2+1\)
Giải phương trình
a)\(\frac{x+5}{x^2-5x}-\frac{x-5}{2x^2+10x}=\frac{x+25}{2x^2-50}\)
b) \(\frac{7}{8x}+\frac{5-x}{4x^2-8x}=\frac{x-1}{2x\left(x-2\right)}+\frac{1}{8x-16}\)
