To factorize an expression, follow these steps:
1. Identify the greatest common factor (GCF) of all the terms in the expression. This is the largest number or variable that can divide evenly into all the terms.
2. Write the GCF outside a pair of parentheses.
3. Divide each term in the expression by the GCF and write the resulting value inside the parentheses.
4. If there are any common factors left in the expression within the parentheses, repeat steps 1 to 3 to continue factoring.
Example:
Let's say we want to factorize the expression 2x^2 + 4x.
Step 1: Identify the GCF, which is 2.
Step 2: Write the GCF outside the parentheses: 2(
Step 3: Divide each term by the GCF and write the resulting value inside the parentheses: 2(x^2 + 2x)
Since there are no more common factors, we have the final factorization: 2(x^2 + 2x).
It is important to note that factoring can become more complex with larger or more complicated expressions, but these steps provide a general guide for basic factorization.
