Question

expand a cube b square, a square b cube, b cube a square. are they all the same?​

Answer 1

Answer:

The plus form is called the sum of cubes, and the formula for this form is this: a^3 + b^3 = (a + b)(a^2 - ab + b^2). Looking at these two forms, you can see that they are practically the same except for the minus and plus signs.

Answer 2

Step-by-step explanation:

Factoring a Sum of Cubes:

a3 + b3 = (a + b)(a2 – ab + b2)

Factoring a Difference of Cubes:

a3 – b3 = (a – b)(a2 + ab + b2)
