Recognize Sum of Cubes: Step Title: Recognize the Sum of CubesConcise Step Description: Identify that the expression is a sum of cubes, which can be factored using the sum of cubes formula: a3+b3=(a+b)(a2−ab+b2).Step Calculation: In this case, g3 is a3 and 27 is b3, where a=g and b=3.
Apply Formula: Step Title: Apply the Sum of Cubes FormulaConcise Step Description: Apply the sum of cubes formula to factor the expression completely.Step Calculation: Using the formula, we get (g+3)(g2−3g+9).
