(a-b) &

(a-b) &

Equal to (a-b) (a ^ 2 + AB + B ^ 2)
A ^ 2 is the second power of A
B ^ 2 is the second power of B

What does a & # 179; - B & # 179; mean? A & # 179; + B & # 179?

What is (a-b) &

(a-b)^3=a^3-3a^2*b+3a*b^2-b^3

A greater than 0, b greater than 0 prove that 1. A + 1 / A is greater than or equal to 2. 2. (a + b) * (1 / A + 1 / b) is greater than or equal to 4
(1 / A + 1 / b) 2 / 2 less than or equal to the following sign AB less than or equal to a + B / 2 less than or equal to the following sign a ^ 2 + B ^ 2 / 2
How to prove that a is greater than 0b is greater than 0. (1 / A + 1 / b) 2 / 2 is less than or equal to the following sign AB is less than or equal to a + B / 2 is less than or equal to the following sign a ^ 2 + B ^ 2 / 2?
