how to solve equation with square root

[Aries]

Hey teerasak,
you could use the modulus:



Otherwise you could save the domain into a variable (e.g. dom) and get the intersection with the equation:



domain(sqrt((x^2)+x-2)+sqrt((x^2)+x-30)-sqrt((2x^2)+2x-32),x) --> dom
solve(sqrt((x^2)+x-2)+sqrt((x^2)+x-30=sqrt((2x^2)+2x-32) and dom,x)
Happy XMas holidays,
