Factor out the GCF from each polynomial.$30x-15$

Step by Step Solution: Step 1. Identify the common factor of 30 and 15, which is 15 Step 2. Write the GCF as a factor outside a set of parentheses Step 3. Divide each term in the polynomial by the GCF and write the result inside the parentheses Step 4. Combine like terms inside the parentheses if possible Final Answer: $15(2x-1)$
