How do we know that numbers a,b and c are in the form of equation (a+b)² or (a-b)² ? |
|
Answer» Answer: If the equation includes the the given VARIABLES as the formulas of the EXPANSION , we can identify the form of formula . For example , if the equation is : (*please note a and b are variables which may have a NUMBER in its place .) a^2 +b^2 + 2ab then it is the form (a+b)^2 and if it is like , a^2 + b^2 - 2ab , then it is the expanded form of (a-b)^2. Hope this helps. Have a NICE day ! |
