plz find value of p and q and do not do substituition method . plz do some other method.. for correct answers i will thank their 5 answers and also follow them.....plz help it is very urgent!!!!! |
|
Answer» Answer: p=1Q=0Step-by-step Explanation: Hii mate :-) It is given that the equation X^2 - px + q = 0 has ROOTS p and q. General form of a quadratic equation x² - (sum of roots)x + (product of roots) = 0 Comparing general form with given equation, we get, Sum of roots = p => p + q = p => q = 0 Product of roots = q => pq = q => pq - q = 0 => q (p - 1) = 0 =>p-1=0 =>p=1 The values of p and q hence found are p = 1, and q = 0. This MAKES the original equation x^2 - x = 0. HOPE IT HELPS, PLEASE THANK, FOLLOW AND MARK AS BRAINLIEST. |
