Webb5 feb. 2024 · The positive root of this equation is √3. Let f (x) = X2 – 3 ∴ ƒ (1) = (1)2 – 3 = 1 – 3 = -2 < 0 (negative) ∴ ƒ (2) = (2)2 – 3 = 4 – 3 = 1 > 0 (positive) ∴ By intermediate value theorem, the root of equation ƒ (x) = 0 lies in interval (1, 2) = (a, b) Initial approximation : (First approximation) 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. signs of pregnancy creamy discharge
