This article embarks on a detailed examination of two specific algebraic expressions: “58. 2x ^ 2 – 9x ^ 2; 5 – 3x + y + 6”. In the realm of mathematics, algebraic expressions serve as the foundation for articulating complex theories, equations, and problems across a wide array of scientific and engineering fields. These expressions, through the use of variables, constants, and algebraic operations, enable the representation of abstract concepts in a structured and universally understood language. Our objective is not only to unravel and simplify these expressions but also to illuminate the fundamental algebraic techniques and principles that underpin such processes.

Delving into Expression 1: 58. 2x ^ 2 – 9x ^ 2; 5 – 3x + y + 6

At first glance, the expression “58. 2x^2 – 9x^2” appears to represent a quadratic polynomial, characterized by its variable raised to the second power. However, a closer inspection reveals a certain ambiguity, particularly in the segment “58. 2x^2”. To demystify this expression, it is essential to dissect its components meticulously:

  1. 58. 2x^2: This segment could be interpreted in two distinct manners. The first interpretation considers it as 58 multiplied by 2x^2, suggesting a straightforward algebraic multiplication. Alternatively, it could be perceived as 58.2 (a decimal number) multiplied by x^2, which introduces a slightly different mathematical operation.
  2. – 9x^2: This term is relatively unambiguous, signifying the subtraction of 9 times the square of from the preceding element in the expression.
The Process of Simplification of 58. 2x ^ 2 – 9x ^ 2
  • First Interpretation (Multiplying 58 by 2x^2): If we adopt the perspective that the expression involves multiplying 58 by 2x^2, the calculation unfolds as follows: 58×2x^2−9x^2 simplifies to , which further simplifies to . This interpretation yields a consolidated quadratic expression in .
  • Second Interpretation (58.2 times x^2): If, on the other hand, we consider the decimal 58.2 as the coefficient of , the expression simplifies differently: 58.2x^2−9x^2 becomes . This approach also produces a quadratic expression but with a coefficient that reflects the decimal calculation.

Exploring Expression 2: 5 – 3x + y + 6

The second expression under our lens, “5 – 3x + y + 6”, is a linear polynomial involving two variables: and . This expression integrates constants and variables in a manner that is straightforward yet requires careful attention to detail for effective simplification.

Methodical Simplification:

Upon combining like terms, which entails grouping constants together and variables together, the process unfolds as follows:

  • Constants: The constants in the expression are 5 and 6. Their summation, 5+6, results in 11.
  • Variables: The variable terms, and , remain as they are since they do not share a common variable and thus cannot be combined.

Consequently, the expression simplifies to . This final form presents a cleaner, more succinct representation of the original expression, highlighting the importance of the simplification process in algebra.
