What is the minimal polynomial of a number?

s = (-b – [b2 – 4ac])/2a. 1. Add them: r + s = (-b + -b)/2a = -b/a. 2. Multiply them: rs = ([-b]2 – [b2 – 4ac])/4a2 = c/a. back. ... byĵ + bzk̂ Magnitudes: |a⃗|=√{ax2 +ay2+az2} |b⃗|=√{bx2 +by2+bz2} Scalar ... 4ac}}/{2a} Work (W), Mechanical Energy (E, Kinetic Energy (K)) ... b = (2siso + ses) (Ved – Ves). c = ses (ses + siso) (Ves – Ved). Taking into account that smax > siso the answer of the sum is. x = {-b - √ (b2 – 4ac)} / 2a. Jul 14, 2023 ... When b2-4ac < 0 then there are no roots at all.
