How do you factor the difference of two perfect cubes?
Example we have this equation a to the third plus b to the third is equal to a plus b times a squared minus a b plus b squared.
How do you factor the difference of cubes?
So we’re subtracting so this is a difference of two cubes. So we’re gonna start off with X. Minus 3 so that’s a minus B then x squared the opposite sign plus 8 times B which is 3 X.
How do you factor perfect cubes?
It’s basically the formula for factor. For a cubed minus b cubed. We get a minus B. Times a squared plus a B plus B squared.
How did you complete factor the sum and difference of two cubes?
The sum or difference of two cubes can be factored into a product of a binomial times a trinomial. That is, x3+y3=(x+y)(x2−xy+y2) and x3−y3=(x−y)(x2+xy+y2) .
What is the example of difference of two cubes?
Example from Geometry:
| x3 | = | y3 + x2(x − y) + xy(x − y) + y2(x − y) |
|---|---|---|
| x3 − y3 | = | x2(x − y) + xy(x − y) + y2(x − y) |
| x3 − y3 | = | (x − y)(x2 + xy + y2) |

How do you find the factor of the difference of two squares?
When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5).
