You solve that by doing the opposite operation. If they add, you subtract. If they subtract you add. If they multiply, you divide. And if they divide you multiply.

Example:

3X=12

12/3=4

Therefore X=4

However, we are going to learn Algebra 2 level Algebra for benefit of our high school audience in this matter. But some of the terms will be found at lower or higher levels.

Pero vamos a aprender el nivel de algebra enseñado en las aulas de bachierrato para beneficiar nuestra audiencia estudiantil. Aunque algunas de las cosas que van a enseñar se cobran en cursos mas adelantados o bajos.

We will learn about the basic way to solve quadratics or functions modeled by a second degree. Ex: 1^2=1 4^2=16 formula is Y=X^2

EX: 2*1^2-4(1)+100= 98 formula es Y=2X^2-4X+100

The four ways are:

Factoring-simplifying the polinomial based on common factors.

X^2-8X+16 What can be multiplied by 16 and add to -8.

Taking the Square Root= This is for easy problems.

EX: (short for example)

4X^2=16

Step 1: If there is any number near the X divide by each side.

(in this case by 4)

Step 2: Take the square root of the number that is left.

X=√4

Step 3: Show the answer as both positive and negative.

X=2 and X=-2 so we write it as x=+-2

Next section we will discuss the other two ways. Please give comments if you have any.
