WebMath Calculus Find the condition which must be satisfied by the coefficients of the polynomial p (x) =x3-px2+qx-r.when the sum of its two zeros is zero. WebThe proof consists of transforming the equation x3 - px2 + qx - r = 0 into the equation X3 - QX + R = 0 by putting x = X + 3p. Then Q = p3p2- q and R = 3pq - r - 27p3 and the result follows from Theorems 2 and 3. As an example, for the cubic with roots 3, - 2, -5 we have p = -4, q = -11, r = 30 and equation (2) has solutions y = 9, 25, 64 ...

WebRoots of the equation px 2 + qx + r = 0 are equal. Formula used: When the roots of quadratic equation ax 2 + bx +c = 0 are equal the D = 0, here D = b 2 - 4ac. Calculation: … WebStep 1: Find the third root. For the cubic equation x 3 + p x 2-q x + r = 0, the sum of the three roots is -p. But it is given that the sum of the two roots is 0. So the third root is -p. … Web24 okt. 2024 · If one root of the equation x² + px + 12 = 0 is 4, while the equation x² + px + q = 0 has equal roots, the value of q is Answer/Explanation 16. a and p are the roots of 4x² + 3x + 7 = 0, then the value of is Answer/Explanation 17.
