Factor $16n - 12n^3$.
Introduction
In algebra, factoring is a process of expressing an expression as a product of simpler expressions. It is an essential skill in mathematics, and it has numerous applications in various fields, including physics, engineering, and economics. In this article, we will focus on factoring the expression 16n - 12n^3.
Understanding the Expression
Before we proceed with factoring, let's understand the given expression. The expression 16n - 12n^3 is a polynomial expression, which consists of two terms: 16n and -12n^3. The first term is a linear term, while the second term is a cubic term.
Factoring Out the Greatest Common Factor (GCF)
One of the most common methods of factoring is to factor out the greatest common factor (GCF). The GCF is the largest expression that divides both terms of the polynomial. In this case, the GCF of 16n and -12n^3 is 4n.
16n - 12n^3 = 4n(4 - 3n^2)
Factoring the Quadratic Expression
The expression 4 - 3n^2 is a quadratic expression, which can be factored further. A quadratic expression is a polynomial of degree two, and it can be factored into the product of two binomials.
4 - 3n^2 = (2 - n\sqrt{3})(2 + n\sqrt{3})
Factoring the Entire Expression
Now that we have factored the quadratic expression, we can factor the entire expression by multiplying the two factors.
16n - 12n^3 = 4n(2 - n\sqrt{3})(2 + n\sqrt{3})
Conclusion
In this article, we have factored the expression 16n - 12n^3 using the method of factoring out the greatest common factor (GCF) and factoring the quadratic expression. The final factored form of the expression is 4n(2 - n\sqrt{3})(2 + n\sqrt{3}). Factoring is an essential skill in mathematics, and it has numerous applications in various fields.
