Question
I. p2 - 19p + 88 = 0   II.
q2Â - 48q + 576 = 0 In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answerÂSolution
I. p2 - 19p + 88 = 0 (p - 11) (p - 8) = 0 p = 11 or 8 II. q2 - 48q + 576 = 0 (q – 24) (q – 24) = 0 q = 24 or 24 Hence, q > p Alternate Method: if signs of quadratic equation is -ve and +ve respectively then the roots of equation will be +ve and +ve. So, roots of first equation = p = 11, 8 So, roots of second equation = q = 24 After comparing roots of quadratic eqution we can conclude that  p < q.
