To factor: The expression
Answer to Problem 1RE
The expression
Explanation of Solution
Procedure used:
To factor an expression containing a common factor:
“1. Find the greatest factor common to each term of the expression.
2. Divide each term by the common factor. Divide mentally if practical.
3. Rewrite the expression as the indicated product of the greatest common factor and the quotient in Step 2”.
Result used:
Distributive property:
For any real number a, x and y,
Calculation:
The given expression is
It is observed that, 5 is a common factor in each term of the exprerssion, so the greatest common factor is 5.
Divide each term in the expression by 5.
Rewrite the given expression as the product of the factor 5 and the sum
On further simplfications,
Therefore, the expression
