Polynomials and More! Recall Practice

Front

What is a polynomial?

Back

A polynomial is a mathematical expression that consists of variables, coefficients, and non-negative integer exponents. For example, 2x^3 - 4x^2 + 3x - 7 is a polynomial.

Front

What is the degree of a polynomial?

Back

The degree of a polynomial is the highest power of the variable in the expression. For example, in the polynomial 4x^3 + 2x^2 - x, the degree is 3.

Front

What is the constant term in a polynomial?

Back

The constant term is the term in a polynomial that does not contain any variables. For example, in 3x^2 + 5x - 2, the constant term is -2.

Front

What does GCF stand for in polynomial factoring?

Back

GCF stands for Greatest Common Factor, which is the largest factor that divides all the terms in a polynomial.

Front

How do you factor a polynomial using GCF?

Back

To factor a polynomial using GCF, identify the largest factor common to all terms and factor it out. For example, in 6x^2 + 9x, the GCF is 3x, so it factors to 3x(2x + 3).

Front

What is the process of substitution in solving systems of equations?

Back

Substitution involves solving one equation for one variable and then substituting that expression into the other equation to find the values of both variables.

Front

What is the formula for exponential growth?

Back

The formula for exponential growth is y = a(1 + r)^t, where a is the initial amount, r is the growth rate, and t is time.

Front

How do you multiply two binomials?

Back

To multiply two binomials, use the distributive property (FOIL method): First, Outer, Inner, Last. For example, (a + b)(c + d) = ac + ad + bc + bd.

Front

What is the result of multiplying (4x + 3)(2x - 1)?

Back

The result is 8x^2 + 2x - 3.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the point(s) where the equations intersect.
