ALGEBRA II Mid-Term (Review/Flashcard/Exam)

Front

What is the line of best fit in linear regression?

Back

The line of best fit is a straight line that best represents the data on a scatter plot. It minimizes the distance between the line and all the data points.

Front

How do you estimate a value using a linear equation?

Back

To estimate a value, substitute the known variable into the linear equation and solve for the unknown variable.

Front

What is polynomial long division?

Back

Polynomial long division is a method used to divide a polynomial by another polynomial, similar to numerical long division.

Front

What is the standard form of a polynomial?

Back

The standard form of a polynomial is written in descending order of the degree of its terms, from highest to lowest.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the polynomial.

Front

What is a leading coefficient?

Back

The leading coefficient is the coefficient of the term with the highest degree in a polynomial.

Front

How do you perform operations with complex numbers?

Back

To perform operations with complex numbers, combine like terms and apply the rules of arithmetic, treating 'i' as the imaginary unit where i^2 = -1.

Front

What is the standard form of a complex number?

Back

The standard form of a complex number is written as a + bi, where a is the real part and b is the imaginary part.

Front

What is the result of subtracting two complex numbers?

Back

To subtract two complex numbers, subtract their real parts and their imaginary parts separately.

Front

What is a polynomial function?

Back

A polynomial function is a function that can be expressed in the form f(x) = a_n*x^n + a_(n-1)*x^(n-1) + ... + a_1*x + a_0, where a_n, a_(n-1), ..., a_0 are constants.
