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