What can be more fun than solving quadratic equations, right? Okay, okay, there are many a lot more exciting things than that. But finding the right solution can improve your analytical skills and help with keeping your attention focus better. If you find this activity immensely boring or rather difficult, this quadratic formula calculator is a great option for you. All you need to do is to type in an equation. The standard way of presenting this sort of task is as follows:
The first question you should ask yourself when looking at a quadratic equation is whether you can factor it. If you can, then there is no need for using long formulas to find the right answer. You simply solve a simple equation where each factor should be equal to 0. In case you don’t see any way of factoring it, it is time to use the quadratic formula:
is called a discriminant. When you calculate it, there can be 3 options for the final result. You can get a positive number and that will lead you to 2 real solutions of the equation. You may get 0 and that means that there will be only one solution. In case the number you get is negative, there will be 2 complex solutions. the solutions of a quadratic equation are often called roots. You can check if your calculation is right by going back to the original expression and substituting your answers instead of X.
How to Benefit from Online Quadratic Formula Calculator
The tools like this one are aimed at making the life of a student easier. To become good at something you need to practice a lot. With the help of this calculator, you will be able to find out if the final result you got is the correct one. Also, you will find a way to continue your calculation process when you get stuck. The step-by-step solution will show you the exact point when you went the wrong way. The only thing you have to be careful with is overusing these online tools.
Will You Need It in the Future?
You might wonder if any of these formulas will be applicable to the real-life situations after you graduate. Even if you won’t choose to pursue the career of a mathematician, you still can benefit from this knowledge. The abstract example of using it can be throwing a ball up in the air. If you know its velocity, the starting position in relation to the ground and keep the gravity in mind, you will be able to calculate when it hits the ground.
One more example might be more useful and applicable. Let’s suppose you start a new business and want to calculate the expected profits you’ll get. To do so, you need to determine the price for the services or products you sell and the number of sales you can expect to get. A quadratic equation will help you do it. If you are not impressed with this two examples, you can always use a quadratic formula calculator to cope with your homework.
