The standard form of a cubic equation with variable x is ax3 + bx2 + cx + d = 0, where a ≠ 0.Equation vs ExpressionExpressions and equations in math are used simultaneously in algebra, but there is a major difference between the two terms. When 2x + 4 is an expression, 2x + 4...
Algebra 2 or Advanced Algebra This is the intermediate level of Algebra. This algebra has a high level of equations to solve as compared to pre-algebra. Advanced algebra will help you to go through the other parts of algebra such as: ...
Elementary AlgebraElementary algebra deals with solving the algebraic expressions for a viable answer. In elementary algebra, simple variables like x, y, are represented in the form of an equation. Based on the degree of the variable, the equations are called linear equations, quadratic equations,...

Parallel lines can be recognised by their equations by checking if their gradients are the same. This may require some rearranging. E.g. Show that y=−2x+4y=−2x+4y=−2x+4 and 4x+2y=94x+2y=94x+2y=9 are parallel. The gradient of the first line is −2−2−2. We need...

As students study for their exams, there are certain very important algebra formulas and equations that they must learn. These formulas are the cornerstone of basic or elementary algebra. Only learning the formulas is not sufficient. The students must also understand the concept behind the formula ...
