Скоротіть дріб: 1. ((x+10)(x-3))/(x+10) = x – 3. 2. (x-14)/(x+5)(x-14) = 1/(x+5) 3. (x^2- 5x)/(x-5) = (x(x-5))/(x-5) = x. 4. x/(x^2+ 6x) = x/(x(x+6)) = 1/(x+6) 5. (x^2- 2x+1)/(x-1) = ((x-1)^2)/(x-1) = x – 1. 6. (x+2)/(x^2+ 4x+4) = (x+2)/((x+2)^2 ) = 1/(x+2) 7. (x^2- 3x+2)/(x-2) = ((x-2)(x-1))/(x-2) = x – 1. 8. (x+1)/(x^2- 2x-3) = (x+1)/((x+1)(x-3)) = 1/(x-3)
