That means that you calculate the cubes of two numbers, and then either add or subtract them.
The sum of two cubes can be factored as below.a3 + b3 = (a + b)(a2 - ab + b2)

8 and 6 have a difference of 2 and a sum of 14.
the sum of two whole numbers are 77 .their difference is 48.what are the two numbers
factoring whole numbers,factoring out the greatest common factor,factoring trinomials,factoring the difference of two squares,factoring the sum or difference of two cubes,factoring by grouping.
That means that you calculate the cubes of two numbers, and then either add or subtract them.
a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2)
There are many different methods to factor polynomials in general; specifically for binomials, you can check:whether you can separate a common factor,whether the binomial is the difference of two squares,whether the binomial is the sum or difference of two cubes (or higher odd-numbered powers)
23 = 8, 33 = 27. Sum 35, difference 19...
That's either the sum or difference of two cubes.
The sum of two cubes can be factored as below.a3 + b3 = (a + b)(a2 - ab + b2)
There is a formula for the difference of two squares. The sum of two squares doesn't factor.
When it is of the form x3 + y3 or x3 - y3. x or y can have coefficients that are perfect cubes, or even ratios of perfect cubes eg x3 + (8/27)y3.
a3 + b3
the 5 kinds of factoring are common monomial factor, difference of two cubes, quadratic trinomial, perfect square trinomial,and difference of two square.
a3 + b3 = (a + b)(a2 - ab + b2) a3 - b3 = (a - b)(a2 + ab + b2
