The application teaches step by step how to solve quadratic equations using Vieta's theorem. The application will be interesting both for those who already know how to solve, and for those who are just beginning to learn how to solve in this way. The app is divided into 10 levels.
- On the first level you have to find numbers, the sum of which will be equal to the one shown.
- On the second level you have to repeat the calculations as on the first level, but now the time is limited.
- At the third level, you will be given a number, the product of which you must find.
- At the fourth level, you repeat the calculation of the third level, but the time is limited.
- At the fifth level you have to find the roots of the provided quadratic equation (x² + bx + c). Using the formulas:
x1 + x2 = -b
x1 * x2 = s
- At the sixth level, level 5 is repeated, but the time is limited.
- At the seventh level, level 6 is repeated, but now the time is even less.
- At the eighth level, you have to solve quadratic equations (ax² + bx + c) by the formulas:
x1 + x2 = -b / a
x1 * x2 = c / a
- At the ninth level, you need to find out if there is a solution to equations in principle.
- The tenth level combines 7, 8 and 9 and gives an infinite number of variations of equations, solving which you earn points.
