What are the fundamental operations in College Algebra?

Some fundamental operations in College Algebra include addition, subtraction, multiplication, division, and exponentiation. These operations are used to manipulate algebraic expressions, solve equations, and simplify mathematical problems involving variables and constants.

How do you simplify algebraic expressions?

To simplify algebraic expressions, you need to combine like terms by adding or subtracting them. Look for terms with the same variables and exponents and then perform the indicated operations. Also, you can apply the distributive property to factor out common factors. Remember to follow the order of operations and simplify any fractions or negative signs. Finally, rewrite the expression in its simplest form by ensuring there are no more like terms to combine.

What is the process for solving linear equations?

To solve a linear equation, identify the variable, isolate it by performing inverse operations to both sides of the equation (such as addition, subtraction, multiplication, or division), simplify the equation, and then solve for the variable by getting it alone on one side. Lastly, check your solution by substituting it back into the original equation to ensure it satisfies the equality.

How do you solve quadratic equations?

To solve a quadratic equation, you can use various methods such as factoring, completing the square, or using the quadratic formula. Factoring involves finding two numbers that multiply to the constant term and add up to the coefficient of the linear term, while completing the square involves rewriting the equation in a square form to solve for the variable. The quadratic formula, (-b ± ?(b^2-4ac)) / 2a, can also be used to solve quadratic equations by plugging in the coefficients of the terms.

What are the steps for solving systems of linear equations?

The steps for solving systems of linear equations involve identifying the variables, choosing a method for solving (such as substitution, elimination, or matrix methods), eliminating a variable by manipulating equations, solving for the remaining variables, and checking solutions by plugging them back into the original equations.

How do you find the domain and range of a function?

To find the domain of a function, you identify all real numbers that you can input into the function. The range of a function, on the other hand, is the set of all possible output values. To determine the range, you evaluate the function for all valid inputs in the domain and list the corresponding outputs. In summary, the domain is the set of input values, while the range is the set of output values that the function can produce.

What is the process for factoring polynomials?

To factor a polynomial, you begin by looking for common factors among the terms and then apply factoring techniques such as the distributive property, grouping, difference of squares, or sum or difference of cubes. If the polynomial has a degree higher than two, you may need to use methods like synthetic division or the quadratic formula for factoring. Continuously check your work to ensure the factors are correct and simplify as necessary.

How do you solve logarithmic equations?

To solve logarithmic equations, you can use properties of logarithms to rewrite the equation in a simpler form. Start by isolating the logarithm on one side of the equation, then apply properties such as the power rule, product rule, or quotient rule to simplify the expression. Finally, solve for the variable by converting the logarithmic form back into exponential form. Make sure to check your solutions to ensure they satisfy any restrictions on the domain of the logarithmic function.

What are the properties of exponents and how are they used in algebraic expressions?

The properties of exponents include the product rule, quotient rule, power rule, zero exponent rule, and negative exponent rule. These properties are used in algebraic expressions to simplify and manipulate terms with powers. They allow us to combine terms with the same base, distribute exponents across multiplication and division, simplify expressions with multiple terms, and handle cases where exponents are zero or negative. Overall, the properties of exponents help in solving equations, factoring polynomials, and working with exponential functions in algebra.

How do you graph linear and quadratic functions?

To graph linear functions, plot the y-intercept and use the slope to find additional points, then draw a straight line connecting the points. For quadratic functions, plot the vertex, the axis of symmetry, and use the shape of the parabola to determine additional points on either side of the vertex, connecting them smoothly to form a curve. Make sure to label the axes and add any necessary details to accurately represent the functions graphically.
