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

Answer 1

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).
