The a 2 - b 2 formula is also known as "the difference of squares formula". The a square minus b square is used to find the difference between the two squares without actually calculating the squares. Let us see the proof of a square minus b square formula. Let us try to solve the equation:. You can understand the a 2 - b 2 formula geometrically using the following figure:.

We have been dealing with different numerals 1, 2, 3, 4 , ….. The arithmetic properties are performed using letters and numbers. Let take an example to better know algebra. Suppose we have to formalize an equation for finding the area of a rectangle. We know there is two unknown dimensions i. An algebraic expression is the combination of numerals and variables. Suppose we have numerals and a variable. Basically, the arithmetic operators separate the terms, and on the basis of the number of terms algebraic expression can be divided into the following types:. If the variable part of two different terms is the same then it is called like terms and if the variable part is not the same then it is called, unlike terms. Similarly 9x and 5y, 2y and 6z, etc are not like terms because they do not have the same variable. For the addition of two algebraic terms, they should have like terms.

Blood types are determined by the presence or absence of certain antigens — substances that can trigger an immune response if they are foreign to the body. Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching. Do you know what blood type is safe for you if you need a transfusion? There are four major blood groups determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. There are very specific ways in which blood types must be matched for a safe transfusion. The right blood transfusion can mean the difference between life and death. Use the interactive graphic below to learn more about matching blood types for transfusions. Also, Rh-negative blood is given to Rh-negative patients, and Rh-positive or Rh-negative blood may be given to Rh-positive patients.
