1.(x + 2)3 = x3 + 3 · x2 · 2 + 3 · x · 22 + 23 =

= x3 + 6x2 + 12x + 8

2.(3x − 2)3 = (3x)3 − 3 · (3x)2 · 2 + 3 · 3x · 22 − 23 =

= 27x 3 − 54x2 + 36x − 8

3.(2x + 5)3 = (2x)3 + 3 · (2x)2 ·5 + 3 · 2x · 52 + 53 =

= 8x3 + 60 x2 + 150 x + 125

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
