What is expansion?

Expansion is the process of unraveling a character expression containing a product form into a sum form.

For example, \( \left(x+1 \right)^{2} \) can be expanded as follows

\[ \left(x+1\right)^2=x^2+2x+1 \]


Example

Example 1

Expand \(\displaystyle \left(x+y+1\right)^2 \).

Solution

\(\displaystyle x^{2}+2xy+2x+y^{2}+2y+1 \)


Example 2

Expand \(\displaystyle \left(x+y\right)^3 \).

Solution

\(\displaystyle x^{3}+3x^{2}y+3xy^{2}+y^{3} \)
