What is Algebra? Algebra helps solve the mathematical equations and allows to derive unknown quantities, like the bank interest, proportions, percentages. We can use the variables in the algebra to represent the unknown quantities that are coupled in such a way as to rewrite the equations. ...
Remember when you were slogging through algebra class thinking, "When am I going to use this in the real world?" Well, welcome to the real world, whereemployers care about your mathematic abilities. Why? Because your numerical reasoning skills and your number sense are directly related to your...
Apolynomialof the second degree is generally called a quadratic polynomial. In elementary algebra, the quadratic formula is the solution of the quadratic equation. There are other ways to solve the quadratic equation instead of using the quadratic formula, such as factoring, completing the square, ...
What is a power in algebra? If p squared is equal to 0.81, what is p? What do you need to add to complete the square for x^2 + 8x? In the notation, assume a is greater than or equal to b. Show that b/a^{2} is less than or equal to k(t) is less than or equal to ...
When pursuing an education in mathematics and algebra, one of the earliest and most important concepts to understand is the associative property, also known as the associative law. This property can be considered an offshoot of another basic mathematical concept known as the commutative property. Bot...

Numerical variables are the variables you’re most familiar with: numbers. For example, those “x” and “y” variables in algebra stand for a number. Categorical variablesarevariablesthat aren’t numbers: they are descriptive. For example, sex (male or female), occupation, school district, st...
In mathematics, a linear equation is defined as a polynomial equation in which the highest exponent of the variables in the equation is 1. These types of equations are called linear, because the graphs of these equations are always lines....
What is a circle? A circle is a geometrical shape. It is defined as having a center, and being the set of all points that are a certain fixed distance from that center. (The fixed distance is called the radius of the circle.) The circle is not of much use in algebra since the equ...
In two-dimensional, the general equation of the circle is represented as {eq}{\left( {x - a} \right)^2} + {\left( {y - b} \right)^2} = {r^2}{/eq} , where {eq}\left( {a,b} \right){/eq} represents the center of the ...
