решить

1) f(x)=x^2/(x-3)^2

2) f(x)=2x^3/x^2-1

3) f(x)=x^2-6x+9/(x-1)^2

4) f(x)=x^2/x^3-1

1)f(x)=x^2/(x-3)^2

0=x^2/(x-3)^2

x=0

2)f(x)=2x^3/x^2-1

0=2x^3/x^2-1

x=1 дробь 2

3)f(x)=x^2-6x+9/(x-1)^2

f(0)=0^2-6x•0+9/(0-1)^2

f(0)=0^2-6•0+9/(-1)^2

f(0)=0-0+9/1

(f)0=9

4)f(x)=x^2/x^3-1

0=x^2/x^3-1

x=1
