Write And Simplify The Following Expression: A Number Times Itself Added To The Product Of 5 And X And Subtracted From The Difference Of 6 And X.
Understanding the Problem
In this article, we will focus on simplifying a complex algebraic expression involving a number times itself, the product of 5 and x, and the difference of 6 and x. The given expression is:
A number times itself added to the product of 5 and x and subtracted from the difference of 6 and x.
Breaking Down the Expression
To simplify the expression, we need to break it down into smaller parts and understand the operations involved. Let's denote the number as 'n'. The expression can be written as:
n^2 + 5x - (6 - x)
Step 1: Simplify the Expression Inside the Parentheses
The expression inside the parentheses is 6 - x. To simplify this, we can rewrite it as:
6 - x = -x + 6
Step 2: Rewrite the Original Expression
Now that we have simplified the expression inside the parentheses, we can rewrite the original expression as:
n^2 + 5x - (-x + 6)
Step 3: Simplify the Expression
To simplify the expression, we need to combine like terms. The expression can be rewritten as:
n^2 + 5x + x - 6
Step 4: Combine Like Terms
The like terms in the expression are 5x and x. We can combine them as:
n^2 + 6x - 6
Simplified Expression
The simplified expression is:
n^2 + 6x - 6
Conclusion
In this article, we simplified a complex algebraic expression involving a number times itself, the product of 5 and x, and the difference of 6 and x. We broke down the expression into smaller parts, simplified the expression inside the parentheses, and combined like terms to arrive at the final simplified expression.
