There are 3 different ways to write a quadratic equation. What are they and when are they most useful?

The quadratic equation formula is used in algebra and can seem a little daunting at first because the formula itself is fairly complex compared with others one might have seen. However, it is quite easy to use the formula once you understand it. There are three different ways to solve quadratic equations. The first includes factoring, though not every math problem can be factored. The second is to complete the square, and the third way to solve these problems is to use the quadratic formula. There are many courses from Udemy that can help you learn in-depth algebra easily, but here is a quick overview of quadratic equations and the quadratic equation formula.

The quadratic equation looks like this: x2 – 3x + 2 = 0. The x is the unknown number and makes an equation that can be solved easily using one of the three ways—factoring, quadratic formula and squares.

Step-by-step explanation:

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
