x^(2)quad " 6."sqrt(x^(2)+4x-5)

Solve sqrt(x^(2)+4x-21)+sqrt(x^(2)-x-6)=sqrt(6x^(2)-5x-39)

Solve the following: (sqrt(x^(2)-5x+6)+sqrt(x^(2)-5x+4))^((x)/(2))+(sqrt(x^(2)-5x+6)-sqrt(x^(2)-5x+4))^(x/2)=2^((x+4)/(4))

Solve sqrt(5x^(2)-6x+8)-sqrt(5x^(2)-6x-7)=1

The number of roots of the equation sqrt(x^(2)-4)-(x-2)=sqrt(x^(2)-5x+6) is

sqrt(x^(2)-4)-(x-2)=sqrt(x^(2)-5x+6)

The number of real solutions of sqrt(x^(2)-4x+3)+sqrt(x^(2)-9)=sqrt(4x^(2)-14x+6)
