Question

The assessment for this lesson is a discussion of a mathematical statement. You will have to determine if the statement is true or false. If it is false, you will explain your reasoning. You will also be asked to respond to at least two of your classmates. Before engaging in the discussion, view the Discussion Guidelines and the Discussion Rubric to ensure that you understand the expectations for this activity. For all real numbers a and b, 2a • b = a2 + b2

Answer 1

only if a-b=0

since (a-b)^2 = a^2-2ab+b^2
so, 2ab = a^2+b^2
