Solving the Mathematical Expression: (4x5+6x4+5x2-x-10)÷(2 x 2+3)
This article will guide you through the process of solving the mathematical expression: (4x5+6x4+5x2-x-10)÷(2 x 2+3). We will break down the steps involved to ensure a clear understanding.
Step 1: Simplify the Numerator
First, we need to simplify the expression within the numerator:
- 4x5 = 20
- 6x4 = 24
- 5x2 = 10
Now, let's substitute these values back into the numerator: (20 + 24 + 10 - x - 10) ÷ (2 x 2 + 3)
Next, combine the constants in the numerator: (54 - x) ÷ (2 x 2 + 3)
Step 2: Simplify the Denominator
Now, let's simplify the denominator:
- 2 x 2 = 4
This gives us: (54 - x) ÷ (4 + 3)
Finally, simplify the denominator: (54 - x) ÷ 7
Step 3: Express the Result
The simplified form of the expression is (54 - x) ÷ 7. This can also be written as (54 - x)/7.
Key Points to Remember
- Order of Operations: Remember to follow the order of operations (PEMDAS/BODMAS) when simplifying expressions: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
- Variable: In this expression, "x" represents an unknown value.
- Final Form: The expression cannot be further simplified without knowing the value of "x".
By following these steps, you can successfully solve the given mathematical expression.
