A new operation is provided: a * b = (a + b) - (a-b) where a and B are rational numbers, then what is a * B + (a + b) * (a-b) equal to What is (a + b) * equal to?

A new operation is provided: a * b = (a + b) - (a-b) where a and B are rational numbers, then what is a * B + (a + b) * (a-b) equal to What is (a + b) * equal to?

∵a*b=(a+b)-(a-b)=2b
∴(a+b)*(a-b)=2a-b)
∴a*b+(a+b)*(a-b)
=2b+2（a-b)
=2a
