The positive root
WebbFor polynomials with real coefficients, it is often useful to bound only the real roots. It suffices to bound the positive roots, as the negative roots of p(x) are the positive roots of p(–x). Clearly, every bound of all roots applies also for real roots. But in some contexts, tighter bounds of real roots are useful. Webb8 juni 2024 · 3∙X N = (3∙0.1291 Ω/0.968 Ω) ∙100 = 40%. X 0 = 5% + 40% = 45%. Xₒ/X 1 = 45%/15% = 3. Note: 60% of I f3ɸ is the maximum ground-fault current for the system to be low-reactance grounded. 9. Find the reactance of a neutral grounding reactor to limit the line-to-ground fault current to 25% of the three-phase fault current.

WebbBy Descartes' rule of signs, the number of sign changes is 2, 2, so there are zero or two positive roots. And f (-x) = -x^3-3x^2+1 f (−x) = −x3 −3x2 + 1 has one sign change, so there is exactly one negative root. To decide whether there are zero or two positive roots, it is a good idea to look at the graph of y=f (x), y = f (x), or to use ...
