What is the distributive property?

The distributive property states that for all real numbers a, b, and c: a(b + c) = ab + ac. In other words, when you distribute a number across a sum in parentheses, you multiply the number by each term inside the parentheses and then add the results. This property is a fundamental concept in algebra and is used to simplify expressions and solve equations.

How do you solve a linear equation?

To solve a linear equation, first isolate the variable by performing inverse operations in the equation. Start by simplifying both sides of the equation by combining like terms and performing operations to separate the variable from constants. Continue solving by performing operations such as adding, subtracting, multiplying, or dividing to get the variable on one side and the constant on the other side. Once the variable is isolated, you have found the solution to the linear equation.

What is the slope-intercept form of a linear equation?

The slope-intercept form of a linear equation is y = mx + b, where m is the slope of the line and b is the y-intercept, the point where the line intersects the y-axis. This form is commonly used to graph and analyze linear equations.

How do you solve a system of equations using substitution?

To solve a system of equations using substitution, start by solving one of the equations for one variable in terms of the other. Then, substitute that expression into the other equation to find the value of the variable. Once you have the value of one variable, substitute it back into one of the original equations to solve for the other variable. Finally, check your solution by substituting both values back into both equations to ensure they satisfy both equations simultaneously.

How do you add and subtract polynomials?

To add or subtract polynomials, you simply combine like terms with similar variables raised to the same powers. Add or subtract the coefficients of these like terms while keeping the variables and their exponents intact. Arrange the resulting expression in descending order of exponents to simplify it further, if necessary. This process allows you to efficiently perform addition and subtraction operations with polynomials.

What is the quadratic formula?

The quadratic formula is x = (-b ± ?(b² - 4ac)) / 2a, where a, b, and c are coefficients of a quadratic equation in the form ax² + bx + c = 0, and x represents the solutions to the equation.

How do you factor a trinomial?

To factor a trinomial, first determine if the trinomial can be factored using methods such as common factors, difference of squares, or trinomials that are perfect squares. If not, use the AC method by finding two numbers that multiply to the product of the leading coefficient (A) and constant term (C), and add up to the middle coefficient (B). Then rewrite the trinomial with these new terms and factor by grouping. Finally, factor out any common factors from each group to arrive at the final factored form of the trinomial.

What are the properties of exponents?

Exponents have a few key properties: the product of two exponential terms with the same base is the base raised to the sum of the exponents, the division of two exponential terms with the same base is the base raised to the difference of the exponents, and raising a power to another power involves multiplying the exponents. Additionally, any nonzero number raised to the power of 0 is equal to 1, and any number raised to the power of 1 is equal to that number itself. These properties are fundamental in simplifying and manipulating expressions involving exponents.

How do you solve inequalities?

To solve inequalities, first isolate the variable on one side of the inequality sign. Treat the inequality sign just like an equal sign when solving. Remember to flip the inequality sign when multiplying or dividing by a negative number. Finally, express the solution using interval notation or as a graph on a number line, depending on the format required.

What is the concept of a function and how is it represented?

A function is a mathematical relation that assigns a unique output value to each input value. It is represented using an equation or formula that describes how the input values are mapped to the corresponding output values. Functions can be graphed on a coordinate plane, where the input values are plotted on the x-axis and the output values on the y-axis. Additionally, functions can be represented using tables, graphs, or even verbal descriptions to show the relationship between the input and output values.
