Solving problems related to quadratic equations from "summary" of RRB ALP Exam PDF-RRB Assistant Loco Pilot Exam-CBT-1-Mathematics Subject eBook by Chandresh Agrawal,Nandini Books
Quadratic equations are a fundamental concept in mathematics that often appear in various competitive exams like the RRB ALP Exam. These equations are of the form ax^2 + bx + c = 0, where x represents the unknown variable, and a, b, and c are constants. To solve problems related to quadratic equations, one must understand the different methods available. One common method to solve quadratic equations is by factoring. Factoring involves finding two numbers that multiply to ac and add up to b in the equation ax^2 + bx + c = 0. By factoring the quadratic equation into two binomials, one can easily find the solutions for x. Another method to solve quadratic equations is by using the quadratic formula. The quadratic formula states that x = (-b ± √(b^2 - 4ac)) / 2a. By substituting the values of a, b, and c into the formula, one can calculate the two possible solutions for x. In some cases, the quadratic equation may not factor easily or have complex roots. In such situations, one can use the method of completing the square to solve the equation. By converting the quadratic equation into a perfect square trinomial, one can find the solutions for x. Moreover, understanding the discriminant of a quadratic equation is crucial for solving problems related to quadratic equations. The discriminant, given by b^2 - 4ac, determines the nature of the roots of the quadratic equation. If the discriminant is positive, the equation has two real and distinct roots. If it is zero, the equation has two real and equal roots. And if the discriminant is negative, the equation has two complex roots. By mastering these methods and concepts related to quadratic equations, one can effectively solve problems that involve quadratic equations in the RRB ALP Exam. Practice and familiarity with these techniques will enhance one's problem-solving skills and boost their performance in the mathematics section of the exam.
