The assessment for this lesson is a discussion of a mathematical statement. You have to determine if the statement is true or false. If it is false, you explain your reasoning.

1.) For all real numbers a and b, 2a • b = a2 + b2


  1. Answer:
    It’s false…. correct is a2+2ab+b2
    Step-by-step explanation:
    This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9. That’s why it’s false.
