SQUARE OF TRINOMIALS | SPECIAL PRODUCTS

Описание: There are binomials or trinomials that when you multiply the products form a pattern. Such are called special products. Using the laws of exponents you will be able to find the product of a) square of a binomial b) sum and difference of binomials, c) cube of a binomial d) square of a trinomial.
B. Square of a Trinomial
(a + b + c)2 = a2 + b2 + c2 + 2ab + 2ac + 2bc
Example: ( 2x + y - 3z)2 = (2x)2 + y2 + (-3z)2 + 2(2x)(y) + 2(2x)(-3z) + 2(y)(-3z)
= 4x2 + y2 + 9z2 + 4xy - 12xz - 6yz
**Square of the 1st term
**Square of the 2nd term
**Square of the 3rd term
**Twice the 1st and 2nd term
**Twice the 1st and 3rd term
**Twice the 2nd and 3rd term
