let binomial be (a + b)now (a+b)3 will be (a+b)(a+b)2

= (a+b)(a2 + 2ab+ b2)

= a(a2+ 2ab+ b2) + b(a2 + 2ab+ b2)

= a3+ 2a2b+ ab2 + a2b + 2ab2 + b3

= a3+ 2a2b+ ab2 + a2b + 2ab2 + b3

= a3 +3a2b + 3ab2 +b3

hope it helped... :D

How do you get the binomial cube of 3m-2n 3?

To calculate the cube of a binomial, you can multiply the binomial with itself first (to get the square), then multiply the square with the original binomial (to get the cube). Since cubing a binomial is quite common, you can also use the formula: (a+b)3 = a3 + 3a2b + 3ab2 + b3 ... replacing "a" and "b" by the parts of your binomial, and doing the calculations (raising to the third power, for example).

What is cube of binomial mean?

The cube of a binomial is the cube of two terms separated by an addition or subtraction sign, such as (2a + 3b) or (ab - cd).For example, (2x - 5y)3 = 8x3 - 40x2y + 50xy2 - 20x2y + 100xy2 - 125y3.The detailed method of expanding this binomial is : (2x - 5y)3 = (2x - 5y)(2x - 5y)(2x - 5y) = (4x2 - 20xy + 25y2)(2x - 5y) = 8x3 - 40x2y + 50xy2 - 20x2y + 100xy2 - 125y3
