Answer 1

Explanation:

A concept map is a diagram that illustrates the relationship between concepts. It is a graphical tool that is often used by graphic designers, engineers and architects to structure and organize knowledge. Concept maps typically depict ideas and information as circles or boxes, which are connected with labeled arrows in a hierarchical structure that is downward-branching.

Answer 2

Answer:

According to the equation ,

(a+b+c) 2 = a 2 +b 2 +c 2+2ab+2bc+2ca

So we get,

Using the formula we can it write it as

(a−2b−3c) 2 =a 2 +(−2b) 2 +(−3c) 2 +2a(−2b)+(2(−2b)(−3c)+2(−3c)a

On further calculation we get,

(a−2b−3c) 2 =a 2 +4b 2 +9c 2 −4ab+12bc−6ac
