How to Describing sequences

A sequence is an ordered list of items, usually numbers. Each item which makes up a sequence is called a “term”. Sequences can have interesting patterns. Here we examine some types of patterns and how they are formed. Examples:...

How to Sum and difference of two cubes of algebra

We now look at two special results obtained from multiplying a binomial and a trinomial: Sum of two cubes: ( x + y ) ( x2 – xy + y2 ) = x (x2 – xy + y2 )...

How to Factorising a quadratic trinomial

Factorising is the reverse of calculating the product of factors. In order to factorise a quadratic, we need to find the factors which, when multiplied together, equal the original quadratic. Consider a quadratic expression of the form ax2 +...

How to Factorising algebra by grouping in pairs

The taking out of common factors is the starting point in all factorisation problems. We know that the factors of 3x + 3 are 3 and (x + 1). Similarly, the factors of 2x2 + 2x are 2x and...

How to Accounting for Removable Discontinuities

Discontinuities at vertical asymptotes can’t be removed. But rational functions sometimes have removable discontinuities in other places. The removable designation is, however, a bit misleading. The gap in the domain still exists at that “removable” spot, but the function...

Determining the equations of vertical and horizontal asymptotes

vertical asymptotes The equations of vertical asymptotes appear in the form x = h. This equation of a line has only the x variable — no y variable — and the number h. A vertical asymptote occurs in the...
