# How do you find the vertical, horizontal or slant asymptotes for f(x)=(2x-4)/(x^2-4) ?
Jun 2, 2016
vertical asymptote x = -2
horizontal asymptote y = 0
#### Explanation:
The first step here is to factorise and simplify f(x).
$\Rightarrow f \left(x\right) = \frac{2 x - 4}{{x}^{2} - 4} = \frac{2 \cancel{\left(x - ... |

# How to find a reflection image
To find a reflection image of a point or a shape, there are some rules you can follow although it is not always possible to follow a rule.
First, let us start with all situations where you can just follow a rule to quickly find the location of the reflected image on the coordinate sy... |

The standard form of a quadratic equation is
ax2 + bx + c = 0
The above formula can be used to solve a quadratic equation in standard form. If the given quadratic equation is not in standard form, convert it to standard form and use the above formula and solve.
Example 1 :
x2 – 5x – 24 = 0
Solution :

## Problem
Let $ABCDE$ be an equiangular convex pentagon of perimeter $1$. The pairwise intersections of the lines that extend the sides of the pentagon determine a five-pointed star polygon. Let $s$ be the perimeter of this star. What is the difference between the maximum and the m... |
# Using Scientific Notation
Updated February 21, 2017 | Factmonster Staff
Sometimes, especially when you are using a calculator, you may come up with a very long number. It might be a big number, like 2,890,000,000. Or it might be a small number, like 0.0000073.
Scientific notation is a way to make these numbers eas... |
# Euclid's Algorithm For Finding The Greatest Common Factor Of 2 Numbers

# Given -4(x - 5) = -30, then what is - 2x + 3 ?
mrsq | Certified Educator
You are given that -4(x-5) = -30. So first, we must solve for x in this equation.
-4(x - 5) = -30
-4*x - (-4)(5) = -30 Distribute -4 to everything in the
parenthesis
-4x + 20 = -30 Simplify
-4x + 20 - 20 = -30 - 20 Use i... |
