If q2– 4pr > 0, the roots of the quadratic equation px2 + qx + r = 0
WebIf the roots of the equation f (x) = x^3 + 3px^2 + 3qx + r = 0 are in H.P. then the roots of the equation f (1/x) = 0 will be in A.P. But f (1/x) = 0 is (1/x^3)+3p (1/x^2)+ 3q (1/x) + r =0 or r x^3 + 3qx ^2 + 3px +1 = 0. Suppose (a-d), a & (a+d) be the roots (taken in A.P.) Webr such that x3 - px2 + qx - r = 0 factorises over the integers. As a second example, we use the result of Theorem 4 to show that the equation 1 1 1 2 15 - + - + - + (3) a b c abc a + b + c has an infinite number of solutions in positive integers a, b, c. Equation (3) may be rewritten as (a + b + c)(bc + ca + ab + 2) = 15abc, scott baker insurance
