Question 907343: a. Find all (real) solutions for x: x − √(6 − x) = 4. If you eliminate a solution, show or explain why.
b. Jill wants to make a substitution in the equation x^(1/3) – 36 = 9x^(1/6)
in order to convert it to a quadratic
equation. Give the substitution (in the form t = …) and the resulting quadratic equation. Do not
solve.
c. After making the substitution u = x^4 in an equation, Jaime found the solutions u = 16 and
u = -4. Find the solution(s) for x.
