Equations in Quadratic Form
Some equations are not quadratic equations, but are in the same form.
To solve equations such as that, make a substitution, solve for the new variable, and then solve for the original variable

These give


No solution
One solution x=
Two solutions x1= x2=
Three solutions x1= x2= x3=
Four solutions x1= x2= x3= x4=
