Resolver, em $\,\mathbb{R}\,$, a inequação $\phantom{X}(0,8)^{{}^{\LARGE 4x^{\large 2}\,-\,x}}\,\geqslant\,(0,8)^{{}^{\LARGE 3(x\,+\,1)}}\phantom{X}$
resposta: $\,\mathbb{S}\,=\,\lbrace x\,\in\,\mathbb{R}\;:\;-\frac{1}{2}\,\leqslant\,x\,\leqslant\,\frac{3}{2}\,\rbrace\;$ ou $\;\mathbb{S}\; =\; [-\frac{1}{2}\,;\,\frac{3}{2}]\,$
