Identify Type and Approach: Identify the type of expression and the approach to factor it.The expression 27v3+1 is a sum of cubes, which can be factored using the sum of cubes formula: a3+b3=(a+b)(a2−ab+b2).
Identify 'a' and 'b': Identify 'a' and 'b' in the sum of cubes formula.In the expression 27v3+1, we can see that 27v3 is the cube of 3v (since (3v)3=27v3) and 1 is the cube of 1 (since 13=1). So, a=3v and b=1.
Apply Sum of Cubes Formula: Apply the sum of cubes formula.Using the values of 'a' and 'b' from Step 2, we apply the sum of cubes formula:27v3+1=(3v)3+13=(3v+1)((3v)2−(3v)(1)+12).
Simplify Factored Expression: Simplify the factored expression.Now we simplify the expression inside the parentheses:(3v+1)(9v2−3v+1).
Check for Further Factoring: Check the factored expression for possible further factoring.The quadratic expression 9v2−3v+1 does not factor further over the integers, so the factoring is complete.
