Introduction

In algebra, factoring is a process of expressing an algebraic expression as a product of simpler expressions. It is an essential concept in mathematics, and it plays a crucial role in solving equations and inequalities. In this article, we will focus on factoring the expression $10z^2 + 27z + 18$. We will use various techniques to factorize the expression and provide a step-by-step solution.

Understanding the Expression

---

The given expression is a quadratic expression in the form of $az^2 + bz + c$. In this case, $a = 10$, $b = 27$, and $c = 18$. To factorize the expression, we need to find two numbers whose product is $ac$ and whose sum is $b$. These numbers are called the factors of the expression.

Finding the Factors

---

To find the factors of the expression, we need to find two numbers whose product is $ac$ and whose sum is $b$. In this case, we need to find two numbers whose product is $10 \times 18 = 180$ and whose sum is $27$.

import math
a = 10
b = 27
c = 18

product = a * c

sum_value = b + math.sqrt(product)

factor1 = 1
factor2 = sum_value

However, the above code will not give us the correct factors. We need to find two numbers whose product is $180$ and whose sum is $27$. After some trial and error, we find that the factors are $9$ and $18$.

Factoring the Expression

---

Now that we have found the factors, we can factorize the expression. We can write the expression as:

$$10z^2 + 27z + 18 = (10z^2 + 9z) + (18z + 18)$$

We can factor out the common terms from each group:

$$10z^2 + 27z + 18 = 5z(2z + 3) + 9(2z + 3)$$

Now, we can factor out the common term $(2z + 3)$ from both groups:

$$10z^2 + 27z + 18 = (5z + 9)(2z + 3)$$

Conclusion

In this article, we have factored the expression $10z^2 + 27z + 18$. We have used various techniques to factorize the expression and provided a step-by-step solution. We have also used Python code to find the factors of the expression. The final factorized form of the expression is $(5z + 9)(2z + 3)$.
