Equations are mathematical expressions that equate two values or expressions, serving as foundational tools for problem-solving in fields like algebra, physics, and engineering.
Key types include:
Linear Equations: Represent straight-line relationships, such as \( ax + b = c \), where solutions are found by isolating the variable.
Quadratic Equations: Involve a variable squared, like \( ax^2 + bx + c = 0 \), solved using methods like factoring or the quadratic formula.
Polynomial Equations: Generalize to higher degrees, such as \( x^3 + 2x^2 – x – 2 = 0 \), with roots determined through various techniques.
Differential Equations: Model rates of change, e.g., \( \frac{dy}{dx} = ky \), essential for dynamics and growth processes.
Systems of Equations: Involve multiple equations, like \( \begin{cases} x + y = 5 \\ x – y = 1 \end{cases} \), solved simultaneously for multiple variables.
Applications span real-world scenarios, from calculating trajectories in physics to optimizing resources in economics, emphasizing their role in analytical reasoning and computation.
