za odpowiedzi razem z rozwiązaniem daję max!
1) 4x^5 - 4x^4 +x^3 = 0
x^3( 4x^2 - 4x + 1) = 0
x^3 = 0
4x^2 - 4x +1 = 0 ; delta= 16- 16 = 0
x= 4+0/ 8 = 1/2
2) = x^{3} + 3x^{2} - 4x -12 \\
(x^{3} + 3x^{2}) - (4x +12) = 0 \\
x^{2}(x+3) - 4(x+3) = 0 \\
(x^{2} -4)(x+3) = 0 \\
x^{2} = 4 \\ x =2; x = -2 ; \\
x= - 3.
