Do you know what [itex]\sqrt{a^2}[/itex] is?nat_94 said:i don't understand these equations and can't find a way to do them from my textbook or any websites please help..
(a) √(2^2+2 x 2+1)
This doesn't make much sense. What does [itex]\sqrt{(25)^2-}[/itex] mean?(b) -√(〖25〗^2-) 〖24〗^2
surely it is not that hard to square? [itex](a+ b)^2= a^2+ 2ab+ b^2[/itex].(c) (7x +y)^2 - (7x - y)^2
An algebra equation is a mathematical statement that uses letters or symbols to represent unknown values, and uses operations such as addition, subtraction, multiplication, and division to solve for the unknown values.
To solve an algebra equation, you need to isolate the variable (the letter or symbol representing the unknown value) on one side of the equation by using inverse operations. This means performing the opposite operation on both sides of the equation until the variable is left alone on one side. Remember to apply the same operation to both sides of the equation to maintain balance.
The basic algebraic operations are addition, subtraction, multiplication, and division. These operations can be used to manipulate equations and solve for unknown values.
To check your answer to an algebra equation, plug in the value you found for the variable back into the original equation. If both sides of the equation are equal, then your answer is correct.
Some common mistakes to avoid when solving algebra equations include forgetting to apply the same operation to both sides of the equation, making miscalculations, and forgetting to check your answer. It is also important to carefully follow the order of operations when simplifying expressions within the equation.
