Two equations are given: A: 2x^2 - 5x + 1 = 0 and B: x^2 - 4x - 2 = 0. Which has the larger discriminant?

Question

Accepted Answer

B, whose D = 24; A has D = 17. A: D = 25 - 4(2)(1) = 25 - 8 = 17. B: D = 16 - 4(1)(-2) = 16 + 8 = 24. Since 24 > 17, B has the larger discriminant. Both are positive but neither is a perfect square, so both equations have irrational roots.
