How to find the real root of a cubic function

The video tutorial explains solving equations by setting them to zero and using inverse operations. It emphasizes factoring for polynomials with multiple variables and demonstrates solving equations with a single variable using inverse operations, including cube roots. The tutorial concludes by identifying real and complex solutions.

Why is factoring emphasized when solving polynomials with multiple variables?

• It is the only method to solve polynomials.

• It simplifies the equation to a single variable.

• It helps in identifying the degree of the polynomial.

• It allows for easier identification of solutions.

What is the primary reason for using inverse operations in this example?

• There is only one variable in the equation.

• The equation is already factored.

• The equation has multiple variables.

• Inverse operations are faster than factoring.

What is the first step in solving the equation using inverse operations?

• Undo addition and subtraction.

• Undo multiplication and division.

• Take the cube root.

• Factor the equation.

What operation is used to solve for the variable after undoing addition and subtraction?

• Multiplication

• Division

• Cubing

• Factoring

What is the real solution for the equation after solving?

• X = 1

• X = -1

• X = -3

• X = 3
