What is a quadratic equation?

Back

A quadratic equation is a polynomial equation of degree 2, typically in the form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.

Front

How do you find the roots of a quadratic equation?

Back

The roots of a quadratic equation can be found using the quadratic formula: x = (-b ± √(b² - 4ac)) / (2a).

What is an outlier in a data set?

Back

An outlier is a data point that differs significantly from other observations in a dataset, which can affect statistical measures like the mean.

Front

How does removing an outlier affect the mean?

Back

Removing an outlier can increase or decrease the mean, depending on whether the outlier is above or below the mean.

Front

What is the formula for the cost of a cab ride?

Back

The cost of a cab ride can be expressed as C = base fare + (cost per mile × number of miles).

Front

If a cab ride costs $4.25 plus $0.35 per mile, how do you calculate the total cost?

Back

Total cost = $4.25 + ($0.35 × number of miles).

Front

What is the difference between the mean and the median?

Back

The mean is the average of a data set, while the median is the middle value when the data is ordered.

Front

What is the difference of squares?

Back

The difference of squares is a mathematical identity that states a² - b² = (a - b)(a + b).

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width: Area = length × width.

Front

What is a polynomial expression?

Back

A polynomial expression is a mathematical expression that consists of variables raised to whole number powers and coefficients.
