Factoring
To factor the binomial , use the sum of cubes pattern: .
Step 1: Confirm the expression fits the pattern. It is a sum, and both terms are perfect cubes, since the first term is and the second term is , which is . Thus, it is a sum of two cubes.
Step 2: Rewrite the terms explicitly as cubes to identify the values for and : and .
Step 3: Substitute these values into the sum of cubes formula:
Step 4: Simplify the expressions inside the trinomial to get the final factored form:
Step 5: Verify the factorization by multiplying the factors together:
The correct factored form is .
