Rewrite 8×3 8 x 3 as (2x)3 ( 2 x ) 3 . Rewrite 1 as 13 . Since both terms are perfect cubes, factor using the difference of cubes formula, a3−b3=(a−b)(a2+ab+b2) a 3 – b 3 = ( a – b ) ( a 2 + a b + b 2 ) where a=2x a = 2 x and b=1 . Simplify.
How do I factor in math?
factor, in mathematics, a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12.
How do you solve factor?
The Solve by Factoring process will require four major steps: Move all terms to one side of the equation, usually the left, using addition or subtraction. Factor the equation completely. Set each factor equal to zero, and solve. List each solution from Step 3 as a solution to the original equation.
