Question

Simplifique os polinômios

A, [2 . (s² - 3s) - s] : s

B,[4 . (u³ - 1) + 4] : 2u²

C, [t² - 3 . (t - 2t²)] : t

Answer 1

$a) \ \frac{2(s^2-3s)-s}{s}=\frac{2s^2-6s-s}{s}=2s-6-1=2s-7\\ \\ b) \ \frac{4(u^3-1)+4}{2u^2}=\frac{4u^2-4+4}{2u^2}=\frac{4u^2}{2u^2}=2\\ \\ c) \ \frac{t^2-3.(t-2t^2)}{t}=\frac{t^2-3t+6t^2}{t}=t-3+6t=7t-3$
