Want to Know How to use Quadratic Equation Calculator?
Most of the activities that we carry out on a day to day basis involve calculations. This is a fact! But feel free to prove me wrong. However, calculations always vary. Some work on accounting calculations. Others calculate speed of the wind, while others calculate the strength of certain materials. But, let me mention a different calculation that most of those who went to high school or are still there are expected to do. I am talking about quadratic equations. These equations are largely found in high school text books but that does not mean cannot be found outside the high school. In fact, chemical industries put to good use the knowledge they have on quadratic equation into mixing some chemicals correctly at the right amount and the right chemical.
So, what is a quadratic equation?
This is an equation that takes the form of ax2 + bx + c, whereby a, b and c is known numbers and they represent the numerical coefficients of the equation given, while x is the unknown variable that we will try to uncover its solution using various methods that are there. Any method used is called a quadratic equation calculator.
Which methods are there to solve quadratic equations?
Since we said that there are methods used to solve quadratic equations, and they are generally called quadratic equation calculators, why can’t we go ahead and name there here? We can start with the commonly used method,
i. Quadratic formula. This is the most convenient method that can be used to solve a quadratic equation. It is best used where factoring of the equation is close to impossible and the maybe the left-hand side of the equation has no perfect square and therefore ruling out the use of complete square method; a method which I will touch on next.
The quadratic formula takes the form of
Therefore x must have two values after calculating the equation using the above method.
ii. The complete square method is another commonly used quadratic equation calculator. It is best applicable in the situations whereby the equation cannot be factored or finding complex roots. It normally converts the quadratic equation from
ax2 + bx + c Form to a(x+d)2 + e = 0
iii. There is another method called factoring. This, however, is rarely used because it is limited to some form of equations. Even then, it produces the results just like any other method except it does not work on many quadratic equations, especially the complex ones or the ones that result in fractional answers.
iv. Graphing method. This is very clear from its definition. It arrives at an answer to the quadratic equation by way of graphs drawing and identifying the points where the line cuts at the x-coordinates.
All of the mentioned methods can be easily understood when you go through the equations, exercises and past papers from online. There is this outstanding site that has educated many, and it still keeps educating more on how to solve math problems like quadratic equation challenges.
