a) The Equation With one Variable:

A variable in mathematics is a symbol that is used in place of a value. The value of a variable depends on the other values in the expression or equation. As a result, the variable can at times change accordingly. Variables can be letters, Greek symbols or combinations of many other symbols.

c) The Equation With Three Variables:

Otherwise it is independent. A linear equation in three variables describes a plane and is an equation equivalent to the equation. where A, B, C, and D are real numbers and A, B, C, and D are not all 0.

Logarithmic

1. To solve a logarithmic equation, rewrite the equation in exponential form and solve for the variable. Example 1: Solve for x in the equation Ln(x)=8. Solution: Step 1: Let both sides be exponents of the base e. The equation Ln(x)=8 can be rewritten .

Polynomial

In mathematics, a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables. An example of a polynomial of a single indeterminate x is x2 − 4x + 7.

Power

Power (physics) In physics, power is the rate of doing work per unit time. It is the amount of energy consumed per unit time. Having no direction, it is a scalar quantity. In the SI system, the unit of power is the joule per second (J/s), known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine.

The General Form:

General Form of Equation of a Line. The "General Form" of the equation of a straight line is: Ax + By + C = 0. A or B can be zero, but not both at the same time. The General Form is not always the most useful form, and you may prefer to use: The Slope-Intercept Form of the equation of a straight line:
