ALG2 How to apply elimination and multiplying one equation to solve

👉 Learn how to factor polynomials by GCF. A polynomial is an expression of the form ax^n + bx^(n-1) + . . . + k, where a, b, and k are constants and the exponents are positive integers. To factor an algebraic expression means to break it...

👉Here is one of the major mistakes I see when students are solving rational equations. Timestamps: 0:00 Intro 0:26 Example #1 1:08 Example #2 2:12 Example #3 3:37 Example #4 4:08 Example #5 5:00 Example #6 6:41 Example #7 7:54 Example #8...

👉 Learn how to add and subtract fractions whose denominators are not the same. Recall that when we want to add or subtract fractions having the same denominator, we add the numerators and retain the (common) denominator. This is...

How to add and subtract fractions.

👉 Learn how to simplify a complex fraction. A complex fraction is a fraction with another fraction or fractions in the numerator and/or in the denominator. To simplify a complex fraction is to reduce the fraction in such a way as there...

In this video we will learn How To Find The Least Common Multiple (LCM) Using Prime Factorization.

In this video lesson, the teacher explains how to find the least common multiple of two numbers by listing their multiples. Through examples and step-by-step instructions, students learn to identify the common multiples and find the...

This video covers the basics of integers. Topics covered include: Multiplication, Multiples, Factors (Divisors), Lowest Common Multiple (LCM), and the Greatest Common Divisor (GCD) also known as the Greatest Common Factor (GCF).

In this video, students learn about the numerator and denominator of a fraction, and how to find the least common multiple to determine the common denominators. The teacher provides examples and guides the students through the process of...

In this video, the teacher explains how to compare fractions by creating common denominators. They use the example of comparing the fractions 2/3, 1/2, and 4/5. The teacher demonstrates how to find the least common multiple of the...

In this video, you will learn how to add mixed fractions with different denominators. By converting the mixed fractions into improper fractions, finding the least common multiple of the denominators, and simplifying the answer through...

In this video, mathematicians are taught how to add and subtract fractions with unlike denominators. They learn the importance of finding a common denominator and how to rename fractions to achieve this. By understanding that the sizes...

In a future time, when AI robots have taken over running pizzerias on a planet orbiting Alpha Centauri, the robot Zigon takes orders and then adds and subtracts fractions before the Pizzamatic-5000 serves up large pepperoni and cheese...

Finding the least common multiple of a set of numbers.

In this video, the teacher explains how to find the least common multiple (LCM) of two or more numbers by creating and comparing a list of multiples for each number. The concept of multiples and skip counting is introduced, and common...

In this video lesson, students learn how to create common denominators between fractions by using equations. It explains the concepts of numerator and denominator, as well as the meaning of equivalent fractions. The lesson also...

In this lesson you will learn how to find the GCF and LCM of two whole numbers by using their prime factors.
