Question

How do you simplify the expression \[4a + 2b + a?\]

Answer 1

Hint: In this question we have to find the simplest form from the above algebraic equation. For that we are going to simplify the equation. Next, we rearrange the variables. And also we are going to add and subtraction in complete step by step solution.
Here, Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. In elementary algebra, those symbols represent quantities without fixed values, known as variables. The letters \[a\] and \[b\] represent the areas of the field.

Complete step by step answer:
Given:
\[ \Rightarrow 4a + 2b + a\]
Next, rearrange the above terms and we get
\[ \Rightarrow 4a + a + 2b\]
Now, we adding the \[a\] coefficient and we get
\[ \Rightarrow 5a + 2b\]

When you simplify an equation, always check for like-terms. \[4a\] and both share a common variable, \[a\]. This makes them like-terms. You can add like terms, creating the sum of \[5a\]. \[2b\], having no term to be able to be added to, stays the same.

This is the required answer of the given equation. 5a + 2b

Note: We have to mind that, variable expressions are expressions that involve variables, which are symbols that represent changing quantities. The value of the expression will change as the value of the variable changes.
To avoid saying exactly the same thing over and over, we use the following to mean the same thing:
Evaluate the expression when \[x = 2\]
Evaluate the expression for \[x = 2\]
Evaluate the expression at \[x = 2\]
Evaluate the expression assuming \[x = 2\]
Evaluate the expression if \[x = 2\]
Also, if there is only one variable in an expression, we don’t always need to mention it:
Evaluate the expression for \[x = 2\]
Evaluate the expression at \[x = 2\].
