=0 is of quadric type. We can solve it by letting 
and 
, and factoring. Or we could solve for 
, square each side, and then solve the resulting quadric equation. Solve the following equations using both methods indicated, and show that you get the same final answers.
quadratic type; solve for the radical, and square.
quadratic type; multiply by LCD
and sides 
and 
.
and 
, use these criteria to find the range of values of 
has two solutions, one solution, or no solution.
