Breaking apart a quadratic expression into a pair of binomials is called:

75% Answer Correctly

	deconstructing
	factoring
	squaring
	normalizing

Solution

To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.

A(n) __________ is two expressions separated by an equal sign.

77% Answer Correctly

	equation
	expression
	formula
	problem

Solution

An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.

Which of the following expressions contains exactly two terms?

83% Answer Correctly

	monomial
	polynomial
	quadratic
	binomial

Solution

A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.

The endpoints of this line segment are at (-2, -7) and (2, 1). What is the slope of this line?

46% Answer Correctly

	1
	-2
	2
	3

Solution

The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, -7) and (2, 1) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(1.0) - (-7.0)}{(2) - (-2)} \) = \( \frac{8}{4} \)
m = 2

What is the area of a circle with a radius of 3?

70% Answer Correctly

	9π
	6π
	64π
	4π

Solution

The formula for area is πr²:

a = πr²
a = π(3²)
a = 9π
