Solving Higher Degree Polynomials

Discuss the role of synthetic division in solving higher order polynomials.

• Synthetic division is only applicable to quadratic polynomials

• Synthetic division simplifies the process of dividing higher order polynomials by linear factors.

• Synthetic division is a method for finding the derivative of a polynomial function

• Synthetic division is used to multiply higher order polynomials

Solve the following equation 0 = x³ -3x²-5x+15

• 3, √5

• 3, √5, -√5

• -3, √5, -√5

• -3, 5i, -5i

What is the relationship between the degree of a polynomial and the number of roots?

• The degree of a polynomial is inversely proportional to the number of roots

• The degree of a polynomial determines the maximum number of roots the polynomial can have.

• The degree of a polynomial determines the minimum number of roots the polynomial can have

• The degree of a polynomial has no impact on the number of roots

Explain the concept of multiplicity of roots in polynomial equations.

• Multiplicity of roots is the same as the degree of the polynomial equation

• Multiplicity of roots indicates the size of the roots in the solution set

• Multiplicity of roots in polynomial equations refers to the number of variables in the equation

• In polynomial equations, multiplicity of roots refers to the number of times a particular root appears in the solution set.

What are the solutions for the polynomial equation

0 = 3 (x + 4) (x + 1) (x - 3)?

• -4, -1, 3

• 3, -3, 4, 1

• 4, 1, -3

• 3, -4, -1, 3

What is the equation in factored form of this graph?

• f(x) = (x-4)(x-1)²(x+2)(x+4)

• f(x) = (x-4)(x+1)²(x+2)(x+4)

• f(x) = (x-4)(x-1)²(x-2)(x+4)

• f(x) = (x+4)(x+1)²(x-2)(x-4)

What is the equation of this graph in factored form?

• (x - 1)(x + 3)²

• (x - 1)²(x + 3)

• (x + 1)²(x - 3)

• (x + 1)(x - 3)²

What does multiplicity of a zero mean?

• Look at the number of terms

• How many times the zero repeats

• Find the sum of all the coefficients

• Ratio your x and y

Which of the following could be the equation of this graph in factored form? (Careful-pay attention to multiplicity.)

• f(x) = (x-4)(x-1)²(x+2)(x+4)
