\(\frac{(a-b)(a+b)}{(a-b)^2}=\frac{a+b}{a-b}\), \(a
e b\).
\(\frac{(4-d)(4+d)}{(d+4)^2}=\frac{4-d}{d+4}\), \(d
e-4\).
\(\frac{x+6}{(x+6)(x+8)}=\frac1{x+8}\), \(x
e-6,-8\).
\(\frac{(x-5)(x-10)}{x-5}=x-10\), \(x
e5\).
\(\frac{(2x-5)(x+1)}{(2x-1)(x+1)}=\frac{2x-5}{2x-1}\), \(x
e-1,\frac12\).
\(\frac{(x+5)(x+10)}{x+10}=x+5\), \(x
e-10\).
\(\frac{(y-4)(y-5)}{(y+6)(y-5)}=\frac{y-4}{y+6}\), \(y
e5,-6\).
\(\frac{(m-3)^2}{(m-3)(m+3)}=\frac{m-3}{m+3}\), \(m
e\pm3\).
\(\frac{(x+6y)(x-y)}{(x-y)(x-3y)}=\frac{x+6y}{x-3y}\), \(x
e y,3y\).
\(\frac{(x-3y)(x+y)}{(x+y)(x+2y)}=\frac{x-3y}{x+2y}\), \(x
e-y,-2y\).
\(\frac{(3x-1)(x+1)}{(x+1)(x^2-x+1)}=\frac{3x-1}{x^2-x+1}\), \(x
e-1\).
\(\frac{(x+3)(x-2)}{(3x+2)(x-2)}=\frac{x+3}{3x+2}\), \(x
e2,-\frac23\).
