For the cubic 3x³ − 4x² − 5x + 2, the sum of the products of its zeroes taken two at a time is:

Question

Accepted Answer

-5/3. For ax^3 + bx^2 + cx + d with zeroes , , : + + = c/a = -5/3 = -5/3 . (Check with the zeroes 2, 1/3 and −1: 2/3 - 1/3 - 2 = -5/3 .) 5/3 drops the sign of c; 4/3 is the sum + + = -b/a ; -2/3 is the product = -d/a .
