The Attempt at a Solution
i tried change of variables so i get [itex]√2x+1 = u[/itex]
then i rearranged that to get [itex]u^2-1/2[/itex]
And i rearrnage original equation and i get this..
[itex]-(u^2-7)/3-u(u^2-1/2)[/itex]
Sorry i am new with this latex thing .. i don treally konw how to use it the sqrt thing so i just lay it out this way
