Below are some of the frequently asked question on the topic Quadratic Equations class 10 mathematics:
The standard form of a quadratic equation is ax² + bx + c = 0 where a not equal to 0.
The quadratic formula is: x = -b±√b²-4ac / 2a It is used to solve quadratic equations when factorization is not possible.
The nature of the roots is determined by the discriminant (Delta = b² - 4ac) ; Delta > 0 means two real and distinct roots. means one real root (repeated). Delta = 0 Delta < 0 means two complex roots.
If the discriminant (Delta = 0) the quadratic equation has exactly one real root (a repeated root).
Quadratic equations are used in various real-life scenarios such as calculating the trajectory of objects, maximizing profit, finding the area of geometric shapes, or solving problems involving speed, distance, and time.
