1+корень 4х+5=2х+2 X- корень х-1 -3=0

1. 1 + sqrt(4х + 5) = 2х + 2, 4x + 5 >= 0, 4x >= -5, x >= -5/4;sqrt(4x + 5) = 2x + 2 - 1;sqrt(4x + 5) = 2x + 1;4x + 5 = 4x^2 + 4x + 1;4x^2 + 4x - 4x = 5 - 1;4x^2 = 4;x^2 = 1;x = +-1.Ответ: -1, 1.х - sqrt(х - 1) - 3 = 0;x - 1 >= 0;x >= 1;-sqrt(x - 1) = 3 - x;sqrt(x - 1) = x - 3;x - 1 = x^2 - 6x + 9;x^2 - 6x - x + 10 = 0;x^2 - 7x + 10 = 0;D = 49 - 40 = 9;x = (7 +- 3)/2;x1 = 5, x2 = 2.Ответ: 2, 5.
