1. Square of a binomial
(a+b)^2 = a^2 + 2ab + b^2
carry the signs as you solve
2. Square of a Trinomial
(a+b+c)^2 = a^2 + b^2 + c^2 + 2ab + 2ac + 2bc
carry the sings as you solve
3. Cube of a Binomial
(a+b)^3 = a^3 + 3(a^2)b + 3a(b^2) + b^3
4. Product of sum and difference
(a+b)(a-b) = a^2 - b^2
5. Product of a binomial and a special multinomial
(a+b)(a^2 - ab + b^2) = a^3-b^3
(a-b)(a^2 + ab + b^2) = a^3-b^3

what are the different special product and factory
with its additional features that make it special
No.
Different formulas were discovered at different times, and by different people. In general, all the commonly-used formulas can be derived by a process called integration.
the special product come from multiply out the bracket you ll need these of ten so its worth knowing them well
