Substitute X = Y³

AKG's suggestion, replace Y3 with X is the best start. Once you do that you will have X2+ 124X- 125 (because Y6= (Y3)2), To factor that, think about the different possible ways to factor 125.
(And don't forget to put Y3 back into the answer in place of X.)
 

1. What is factoring in college algebra?

Factoring in college algebra is a process of finding the factors of a polynomial expression. It involves breaking down a polynomial into smaller parts that can be easily multiplied together to get the original expression. Factoring is used to solve equations, simplify expressions, and find the roots of a polynomial.

2. Why is factoring important in college algebra?

Factoring is an essential skill in college algebra because it helps to simplify complex expressions and solve equations. It also allows us to find the roots of a polynomial, which is crucial for graphing and solving real-world problems. Furthermore, factoring is a fundamental building block for more advanced mathematical concepts such as logarithms and rational expressions.

3. What are the different methods of factoring in college algebra?

There are several methods of factoring in college algebra, including the GCF (greatest common factor) method, grouping, difference of squares, and trinomial factoring. The method used depends on the type of polynomial expression and the number of terms it contains. It is essential to learn and understand each method to effectively factor polynomials.

4. How do I know when to use factoring in college algebra?

Factoring is typically used when we need to simplify a polynomial expression, solve an equation, or find the roots of a polynomial. It is also used when we are asked to factor a specific expression or solve a problem that involves factoring. It is important to recognize when factoring is needed and to understand which method to use for a particular type of polynomial.

5. What are some tips for factoring in college algebra?

To effectively factor polynomials in college algebra, it is helpful to follow these tips:
- Always look for the greatest common factor first.
- Familiarize yourself with the different factoring methods and practice using them.
- Pay attention to the signs and coefficients of each term in the polynomial.
- Check your answer by multiplying the factors together to ensure they equal the original expression.
- Practice, practice, practice! Factoring requires repetition to master.
