One Variable Linear Equation

One Variable Linear Equation is an open mathematical sentence with one variable. The general form of a one-variable linear equation is ah+b=ch+d, where h is the variable, a, b, c and d are real numbers. As a real example, there is water in 1/2 part of a bowl that will be filled with 100 ml will become 2/3 parts of water in a bowl, this sentence when written in mathematical form becomes 1/2 m + 100 = 2/3 m, with a value m unit ml. From the real example above, the equation obtained is called a one-variable linear equation, which means an equation whose variable is to the power of 1 and only has one variable. To solve this is very easy, the method is: find the variable term on the left and find the constant on the right, then easily get the value of the variable. The moving term will change the + sign to - and vice versa.  As an example, in the above equation 1/2 m+100=2/3m, we move 2/3m and 100 to: 1/2m-2/3m=-100 -1/4m=-100 m=400 So, the capacity of the bowl is 400 ml.  Thus a short p

What are irrational number?

Welcome visitors to the mathematic.my.id blog,,  In this post, we will explain about irrational numbers clearly.  Irrational numbers are numbers in the form of roots, roots to the power of 3, 4, ... where the value is not an integer. Example: sqrt(2), sqrt[3](7), sqrt[6](15) and so on.  Thus this short post. See you in another post.

Quadratic Equation

Welcome visitors, On this occasion will be discussed about the material quadratic equations. Quadratic equations are equations with the general form: $$ax^2+bx+c=0$$ where $a, b, c$ are real numbers and $a$ are not zero. The coefficient $x^2$ is called the initial value, the coefficient $x$ is called the middle value and the constant is called the final value. The way to solve this is by factoring and using the abc formula. Example 1: Find the square root of $x^2+3x+2=0$. Answer: We use the factoring method, in this factoring method the initial value must be 1, if not 1 then the final value becomes $ac$ and the initial value becomes 1, then find 2 numbers whose product is the final value and the result is the middle value, after getting two that number then divide by the value $a$. So that we get: $$(x+1)(x+2)=0$$ $x=-1$ and $x=-2$. Example 2: Find the square root of $15x^2-2x-24=0$. Answer: The equation becomes: $$x^2-2x-360=0$$ $$(x+18)(x-20)=0$$ $x=-18$ an
