How do you find the roots of a polynomial?

• By setting the polynomial equal to zero and solving for the variable.

• By factoring the polynomial into linear terms only.

• By taking the derivative of the polynomial and finding critical points.

• By substituting random values into the polynomial until it equals zero.

What is a binomial?

• A polynomial with exactly one term.

• A polynomial with exactly two terms.

• A polynomial with three or more terms.

• A type of linear equation.

Factor the polynomial: 5x² - 13x + 6

• (x - 2)(5x - 3)

• (5x - 2)(x - 3)

• (x - 1)(5x - 6)

• (5x + 2)(x - 3)

Find the difference: (3 - 2x + 2x²) - (4x - 5 + 3x²)

• -x² - 6x + 8

• -x² - 5x + 7

• -x² - 7x + 9

• -x² - 6x + 7

What is the quadratic formula?

• x = (-b ± √(b² - 4ac)) / (2a)

• x = (b ± √(b² + 4ac)) / (2a)

• x = (-b ± √(b² + 4ac)) / (2a)

• x = (b ± √(b² - 4ac)) / (2a)

Factor: x² – 5x – 24

• (x - 8)(x + 3)

• (x - 6)(x + 4)

• (x - 12)(x + 2)

• (x - 10)(x + 5)

What is the difference between a monomial and a polynomial?

• A monomial is a single term, while a polynomial is a sum of two or more terms.

• A monomial can have multiple terms, while a polynomial is always a single term.

• Both monomials and polynomials are the same, just different names for the same concept.

• A monomial is a type of polynomial that has only one variable.

Which binomial is a factor of the polynomial 3x² + 7x + 2?

• (3x + 1)

• (3x + 2)

• (x + 1)

• (x + 2)

What is the degree of the polynomial 4x³ - 2x² + 7?

• 1

• 2

• 3

• 4

What is the process of combining like terms?

• Adding or subtracting coefficients of terms with different variables.

• Combining terms with different powers of the same variable.

• Adding or subtracting coefficients of terms that have the same variable raised to the same power.

• Multiplying coefficients of terms with the same variable.
