Fill in the blank boxes using the following short computational formulas so that it corresponds a box to each term .

The purpose of this exercise is to learn about short computational formulas and the results are not important.

( a + b )^{ 3 } = a^{ 3 } + 2a^{2 }b + 2ab^{ 2 } + b^{ 3 }

( a - b )^{ 3 } = a^{ 3 } - 2a^{2 }b + 2ab^{ 2 } - b^{ 3 }

a^{ 3 } + b^{ 3 } = ( a + b )( a^{ 2 } - ab + b^{ 2 } )

a^{ 3 } - b^{ 3 } = ( a - b )( a^{ 2 } + ab + b^{ 2 } )

By learning math, you learn to think.
