The book answer appears simple and unimpeachable to me.MatinSAR said:
Thanks for your reply.PeroK said:
That looks like an alternative. ##a,b,c## are related, so there must be several different identities hidden there.MatinSAR said:
Thank you again. For taking time to help me...PeroK said:
Yes, it is a poor question. E.g. you could solve the quadratic to find x as a function of a then plug that in.PeroK said:
Algebraic expressions are used in many fields, including finance, engineering, and computer science. Examples of real-life applications include calculating interest rates, designing structures, and writing computer programs.
Algebraic expressions can be used to represent and manipulate quantities in mathematical equations. By solving these equations, we can find unknown values and solve problems in various contexts.
An algebraic expression is a mathematical phrase that contains numbers, variables, and operations. An algebraic equation, on the other hand, contains an equal sign and is used to show the relationship between two expressions.
The most common algebraic operations used in applications include addition, subtraction, multiplication, and division. Other operations, such as exponents and radicals, are also frequently used in more advanced applications.
Understanding algebraic expressions can help us make sense of and solve problems in everyday life. For example, we can use algebra to calculate discounts while shopping, determine the best cell phone plan, or even plan a budget.
