Special products
Special products is a Mathematical term in which factors are combined to form products. It is called "special" because they do not need long solutions.
The Different types of Special Products
1) Square of a Binomial
- this special product results into Perfect Square Trinomial (PST)
(a+b)^2= a^2 + 2ab + b^2
(a-b)^2= a^2- 2ab + b^2
2) Product of sum & difference of two Binomials
-this results to Difference of two squares
(a+b)(a-b) = a^2 - b^2
3) Square of Trinomial
- this results to six terms
(a+b+c)^2 = a^2 + b^2 +c^2 + 2ab + 2ac + 2bc
4) Product of Binomials
-this results to General Trinomial
-You can use the F.O.I.L. ( first, outer, inner, last) method or parrot's Beak
(a+b) (c+d) = ac + (bc + ad) + bd
