Question

cac 5 ) A=( 1 sqrt x -2 + 1 sqrt x +2 ). x-4 sqrt x; A = ((x + 3sqrt(x))/(sqrt(x) + 3) - 2)((x - 1)/(sqrt(x) - 1) + 1); A = ((sqrt(a) - 2)/(sqrt(a) + 2) - (sqrt

Answer

DATE NO A = -4 2 ) - 2) 9-9 = ((a-2)^ 2 -(1a+2)^ 2 (a-2)^ 2; = underline a-9 sqrt a+9 -a-4 sqrt a-9 * a-9 sqrt a; = -8 sqrt a sqrt a =-8; A = (sqrt(x) + 3)/(sqrt(2) + 1) +
