Solving Radical Equations Quiz

What is the first step in solving the equation x = sqrt(30 - x)?

• Square both sides

• Isolate the radical

• Factor the equation

• Add x to both sides

After squaring both sides of x = sqrt(30 - x), what type of equation do we get?

• Quadratic equation

• Linear equation

• Cubic equation

• Exponential equation

What is an extraneous solution?

• A solution that is complex

• A solution that is negative

• A solution that does not satisfy the original equation

• A solution that satisfies the original equation

In the equation V = sqrt(5V), what is the GCF used for factoring?

• V

• V^2

• 5

• 1

What are the solutions for the equation V = sqrt(5V)?

• V = 0 and V = 5

• V = 0 and V = -5

• V = 5 and V = 10

• V = 5 and V = -5

In the third example, what is the equation after moving all terms to one side?

• m^2 + 3m + 40 = 0

• m^2 - 3m + 40 = 0

• m^2 + 3m - 40 = 0

• m^2 - 3m - 40 = 0

What is the correct solution for the equation m^2 = -3m + 40?

• m = -8

• m = -5

• m = 5

• m = 8
