Решите уравнения
а)(х-1)^2(х+2)=0
б)х^2-1)(x-3)=0
d)(x-4)^2(x-3)=0
u) (x^2-4)(x+1)=0

(x - 1)^2( x + 2) = 0x - 1 = 0x = 1x + 2 = 0x = - 2(x^2 - 1)(x - 3) =0( x - 1)(x + 1)( x - 3) = 0x - 1 = 0x = 1x + 1 = 0x = - 1x - 3 = 0x = 3(x - 4)^2(x - 3) = 0x - 4 = 0x = 4x - 3 = 0x = 3(x^2 - 4)(x + 1) = 0( x - 2)(x + 2)(x + 1) =0x - 2 = 0x = 2x + 2 = 0x = - 2x + 1 = 0x = - 1
