Algebra ACT Math Prep: Exponential Equations

Posted on October 25, 2024October 25, 2024 by Nathaniel

In this ACT Math video, we cover Exponential Equations. In these types of problems, you have bases that are raised to powers and we need to find the value of x that makes both sides equal to each other.

We show how to change the bases to make the problem easier to solve. We also show how to use the answer choices to solve the problem.

The example used in the video will be based off the following ACT math problem:

This is the practice exercise we will work out in the video:

This practice problem is considered a MEDIUM difficulty problem.

Algebra ACT Math Prep: Quadratic Equations

In this ACT Math prep video, we cover quadratic equations, which are polynomial equations where the highest degree or power is x². We cover various methods for solving the problem which includes factoring, solving by square roots, using the quadratic formula, as well using the discriminant.

The example used in the video will be based off the following ACT math problem below:

This practice problem is considered a MEDIUM to HARD difficulty problem.

Algebra ACT Math Prep: Geometric Series

Posted on September 25, 2024September 29, 2024 by Nathaniel

In this ACT Math prep video, we get into the topic of geometric sequences and series. A geometric series occurs when numbers in a multiplication pattern are added together. When there are few terms in a geometric series to add up, it is easy to use a basic calculator. When you need to add up a lot of terms, a formula can to be used to quickly get the sum.

The example used in the video will be based off the following ACT math problem below:

This practice problem is considered a MEDIUM difficulty problem.

Algebra ACT Math Prep: Distance, Rate & Time

Posted on September 23, 2024September 29, 2024 by Nathaniel

In this ACT Math prep video, we cover a distance, rate and time problem. Many students have a hard time with these types of problems because they are usually in the form of long word problems that require careful reading comprehension. In this ACT math example, we break down a trip into parts to get the desired solution.
