This self checking worksheet uses a quadratic base, but the equations have different exponents as well as an additional step to solve at the end. Some are whole numbers, some fractions and some negative whole numbers: 3(2x+4)^(2/5) - 4(2x+4)x^(1/5) - 4 = 0 and (2x)^8 - 34(2x)^4 + 64 = 0. The students must be able to work with radicals as well as factor trinomials. The student must check the solutions. When finished, the student will learn an obvious statement.
