If one of the roots of $$ax^2+bx+c=0$$ is half of the other root, then which of the following conditions must be true?
If the root is p then the sum of the roots = 3p/2 = -b/a => p=-2b/3a, and product of roots is $$p^2/2=c/a$$. $$(-2b/3a)^2=2c/a $$=>$$ 4b^2/9a^2 = 2c/a => 2b^2=9ac$$
Yes, Quadratic Equations is an important algebra topic in SNAP Quantitative Aptitude. Questions from this area test conceptual understanding, algebraic manipulation skills, and problem-solving ability.
SNAP does not have a fixed number of questions from Quadratic Equations. However, candidates can expect direct or concept-based questions involving roots, factorization, and quadratic expressions.
SNAP may include questions on solving quadratic equations, finding the nature of roots, factorization, discriminants, relationships between roots and coefficients, and application-based algebra problems.
Start by learning the fundamental concepts of quadratic equations, including factorization methods and root properties. Practice a variety of questions, solve problems from SNAP Previous Papers, and regularly attempt SNAP Mock Tests to improve speed and accuracy.
The difficulty level is generally easy to moderate. Most questions are concept-based and can be solved quickly if candidates have a strong understanding of formulas, factorization techniques, and algebraic principles.
Cracku's SNAP Quadratic Equations Questions are designed according to the latest SNAP exam pattern and difficulty level. They provide topic-wise practice questions, detailed solutions, shortcut methods, and performance analysis to help aspirants strengthen their concepts and improve their scores.
