2)x^2-3x/(x-2)•(x+2):x^2-3/x^2+2x
x^2-3x/(x-2)•(x+2)•x^2+2x/x^2-3
x^2-3x/(x-2)•(x+2)•x•(x+2)/x^2-3
x^2-3x/x-2•x/x^2-3
x•(x^2-3x)/(x-2)•(x^2-3)
x^3-3x^2/(x-2)•(x^2-3)
x^3-3x^2/x^3-3x-2x^2+6
x^3-3x^2/x^3-2x^2-3x+6
6.a^2+c^2-ac/c:a-c/2c-a
a^2+c^2-ac/c•2c/a-c-a
a^2-2ac+c^2/c•2c/a-c-a
(a^2-2ac+c^2)•2/a-c-a
(a-c)^2•2/a-c-a
(a-c)•2-a
2a-2c-a
a-2c
