Let’s understand about the Quadratic Equation in detail.

**Question : 1****The equation x**^{2}– px – 60 = 0, has two roots ‘a’ and ‘b’ such that (a – b) = 17 and p > 0. If a series starts with ‘p’ such that the consecutive terms are 4 more than the preceding term is formed, then find the product of 2^{nd}and 4^{th}terms of such series.**Answer: 209****Question : 2****The equation q**^{2}- 17x + C = 0, has two roots ‘x’ and ‘y’ such that (x – y) = 7. Find an equation which is equal to thrice of the given equation.**Answer: 3q^2 + 51q + 180****Question : 3****Which of the following statements is/are true?**I. 2(p + s) = 12
