Identify GCF: Identify the greatest common factor (GCF) of the terms in the expression.The terms are 18 and 45x. The GCF of 18 and 45 is 9 because 9 is the largest number that divides both 18 and 45 without leaving a remainder.
Factor out GCF: Factor out the GCF from each term in the expression.The expression 18+45x can be rewritten as 9(2)+9(5x) by dividing each term by the GCF, which is 9.
Write factored expression: Write the factored expression.After factoring out the GCF, the expression becomes 9(2+5x).
