Sal Khan shows many examples of how to solve an equation using one step, multi-step, and variables on both sides. He tackles many word problems and gives you plenty of time to complete interactive practices. He goes from beginners to expert level (solving for a variable and manipulating formulas). Last, he covers absolute value equations and introduces the distributive property.
Sal Khan offers more tutorial videos on solving inequalities using one step, multi-step, and variables on both sides. He shows many examples of compound and absolute value inequalities.
Sal Khan offers more lessons on functions to gain a deeper understanding of this chapter, and in future math courses. He goes beyond the textbook, but it's a good practice to learn advanced function notation, recognizing functions, knowing domain and range, evaluating functions, and graphing functions.
Sal Khan offers detailed lessons on the coordinate plane, ordered pairs, graphing solutions to equations, linear relationships, x and y intercepts, proportional relationships, rates, slopes, graphing linear equations using different forms, and analytic geometry (parallel and perpendicular lines), and graphing linear inequalities. He has plenty of interactive practices to master skills on linear functions, which are used in future mathematics courses such as Geometry, Algebra 2, Precalculus, and Calculus.
Sal Khan teaches you how to solve system of linear equations by substitution, elimination, and graphing. He solves various word problems dealing with systems of equations and inequalities.
Founder, Sal Khan offers free tutorial videos on exponent expressions and equations. He explores properties of exponents, negative and positive exponents, simplifying exponents, fractional exponents, radical expressions, and radical equations. If you need help with Chapter 9, feel free to browse through this portion of Khan Academy. Practice your skills with his interactive activities.
Sal Khan explores the word of monomials and polynomials by distributing and factoring. He shows examples of factoring simple expressions to factor by grouping to factor quadratics in two variables. He introduces the basic foundation of polynomial functions including, but not limited to, terminology, combining (adding and subtracting) like terms, and multiplying polynomials. Select a video and skill that applies to your needs (homework, quiz, or test) and we hope this helps!
Sal Khan covers how to solve quadratic equation through various methods such as taking square root, factoring, completing the square, and quadratic formula (quadratic equation). He graphs quadratic equations in standard form and in vertex form. He also covers quadratic inequalities.
Sal Khan covers exponential functions in Algebra 2 course; it is also found in the later chapters of Algebra 1. It's a good practice to know it now so you are better prepared for Algebra 2.
