Solving the Equation (-5)^2 - 2*(-9) + 6
This article will guide you through the steps of solving the equation (-5)^2 - 2(-9) + 6*.
Understanding the Order of Operations
To solve this equation correctly, we need to follow the order of operations, often remembered by the acronym PEMDAS or BODMAS. This stands for:
- Parentheses (or Brackets)
- Exponents (or Orders)
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Step-by-Step Solution
- Exponents: First, we calculate (-5)^2, which is (-5) * (-5) = 25.
- Multiplication: Next, we perform the multiplication: -2 * (-9) = 18.
- Addition: Finally, we add all the terms together: 25 + 18 + 6 = 49.
