This Questions tests on Simplifying Algebraic Expressions
Algebraic Expressions
Algebraic Expressions are expressions made up of both numbers and alphabets which are normally variables. Just like Numerical Expresions, Algebraic Expressions can be simplified by using order of operations as well.
Example: 4x + 7(x - 6) = 4x + 7x - 42 = 11x - 42
Application
Using the above concept, we can simplify the given expression:
(Note that a and b are separate variables(
