In this video I present a set of problems to help prepare for learning about rational functions in precalculus. While rational functions is explored in Algebra 2 I decided to make it a separate unit in precalc based on how many students...

In this video playlist I show you how to solve different math problems for Algebra, Geometry, Algebra 2 and Pre-Calculus. The video will provide you with math help using step by step instruction. Math help tutorials is just what you...

👉 Learn how to simplify expressions using the quotient rule and the negative exponent rule of exponents. The quotient rule of exponents states that the quotient of powers with a common base is equivalent to the power with the common base...

There are some pretty common mistakes I see students make time and time again when simplifying radicals. In this video I am going to highlight the top three.

👉 Learn about solving exponential equations. Exponential equations are equations involving exponents. To solve an exponential equation, we express the terms in both sides of the equality sign as a single term. Then, we express the single...

Expand the binomial completely using binomial expansion and pascals triangle

👉 Learn how to solve quadratic equations using the quadratic formula. A quadratic equation is an equation whose highest power on its variable(s) is 2. The quadratic formula is a formula which can be used to find the roots of (solve) a...

Learn how to identify the domain and range of functions from equations. To do this we will need to sketch the graph of the equation and then determine how low and how high the graph travels for the range and how far left and how far...

👉 Learn about dividing by synthetic division when there is a missing power. Synthetic division is a method of dividing polynomials by linear expressions. To divide using synthetic division, we equate the divisor to 0 and then solve for...

Students often hate completing the square, it can be confusing or maybe they understand the process but then get tripped up on more difficult examples. In this video we will cover the basics of completing the square

👉 Learn how to graph a quadratic equation in vertex form by applying transformations such as horizontal/vertical shift, horizontal/vertical compression stretch and reflections. If the equation is not in vertex form, then we will apply...

Composition of a quadratic function to a square root function
