Chapter 8 Review #1

What term is used to describe an expression consisting of two terms?

• Monomial

• Binomial

• Trinomial

• Polynomial

Answer explanation

A binomial is used to describe an expression consisting of two terms, making it the correct choice in this scenario.

What property is demonstrated by the equation x(y + z) = xy + xz?

• Zero Product Property

• Distributive Property

• Associative Property

• Commutative Property

Answer explanation

The equation x(y + z) = xy + xz demonstrates the Distributive Property, which states that a(b + c) = ab + ac.

What is the term for the highest or lowest point on a parabola?

• Axis of symmetry

• Vertex

• Focus

• Directrix

Answer explanation

The term for the highest or lowest point on a parabola is called the Vertex.

What do you call a quadratic equation that has been rewritten to show the x-intercepts?

• Standard form

• Factored form

• Vertex form

• Exponential form

Answer explanation

A quadratic equation rewritten to show the x-intercepts is in factored form, making it easier to identify the roots of the equation.

What is the name of the property used to find the roots of a quadratic equation (x intercepts)?

• Factoring

• Communicative Property

• Zero Product Property

• Associative Property

Answer explanation

The Zero Product Property is used to find the roots of a quadratic equation (x intercepts). It states that if the product of two factors is zero, then at least one of the factors must be zero.

What is the y intercept?

• (3,0)

• (0,3)

• (1,0)

• (3,0)

Answer explanation

The correct y-intercept is (0,3) because it represents the point where the graph intersects the y-axis at y=3.

What term is used to name an expression containing 3 terms?

• Monomial

• Binomial

• Trinomial

• polynomial

Answer explanation

Trinomial is the term used to name an expression containing 3 terms.

Name the line of symmetry for this parabola.

• y=0

• y=-4

• x=2

• x=0

Answer explanation

The line of symmetry for a parabola is the vertical line passing through the vertex. In this case, the line of symmetry is x=0, as the parabola is symmetric about the y-axis.

What is the square root of this term?

• 2x

• x

• 4x

• 

What is the square root of 25?
