Introduction
Factoring expressions is a fundamental concept in algebra that involves breaking down an expression into simpler components. It is a crucial skill for solving equations, graphing functions, and simplifying complex expressions. In this article, we will explore the factored form of a given expression and provide a step-by-step guide on how to factor it.
What is Factoring?
Factoring is the process of expressing an expression as a product of simpler expressions, called factors. These factors can be numbers, variables, or a combination of both. Factoring an expression can help us simplify it, identify its roots, and solve equations.
The Given Expression
The given expression is:
27t3−36t2−12t+16
Our goal is to factor this expression into the form:
(□)(□∨)(□∨)
Step 1: Factor Out the Greatest Common Factor (GCF)
The first step in factoring an expression is to identify the greatest common factor (GCF) of all the terms. The GCF is the largest expression that divides all the terms evenly.
In this case, the GCF of the given expression is 3t^2.
import sympy as sp

t = sp.symbols('t')
expr = 27t**3 - 36t**2 - 12*t + 16
gcf = sp.gcd(expr, t**2)
print(gcf)
Step 2: Factor the Expression
Now that we have factored out the GCF, we can focus on factoring the remaining expression.
The expression can be rewritten as:
3t2(9t−12)−4(9t−12)
We can see that the expression is a difference of squares, which can be factored as:
(3t2−4)(9t−12)
# Factor the expression
factored_expr = sp.factor(expr)
print(factored_expr)
Step 3: Write the Factored Form
Now that we have factored the expression, we can write it in the desired form:
(3t2−4)(9t−12)
This is the factored form of the given expression.
Conclusion
Factoring expressions is a crucial skill in algebra that involves breaking down an expression into simpler components. In this article, we explored the factored form of a given expression and provided a step-by-step guide on how to factor it. We identified the greatest common factor (GCF) of the expression, factored the remaining expression, and wrote the factored form in the desired form.
Final Answer
The factored form of the expression is:
(3t^2 - 4)(9t - 12)$<br/>

Introduction
Factoring expressions is a fundamental concept in algebra that involves breaking down an expression into simpler components. In our previous article, we explored the factored form of a given expression and provided a step-by-step guide on how to factor it. In this article, we will answer some frequently asked questions about factoring expressions.
Q: What is the greatest common factor (GCF)?
A: The greatest common factor (GCF) is the largest expression that divides all the terms of an expression evenly. It is the first step in factoring an expression.
Q: How do I identify the GCF of an expression?
A: To identify the GCF of an expression, you need to find the largest expression that divides all the terms of the expression evenly. You can use the following steps:
- List all the factors of each term in the expression.
- Identify the common factors among all the terms.
- Choose the largest common factor as the GCF.
Q: What is the difference of squares formula?
A: The difference of squares formula is:
