varog frumos sa ma ajutați xla a doua -3x+2>0 varog urgent varog frumos

Answer 1

   
[tex]\displaystyle\\ \text{Rezolvam ecuatia atasata a acestei inecuatii.}\\\\ x^2 - 3x+2=0\\\\ x_{12}= \frac{-b\pm \sqrt{b^2-4ac} }{2a}= \frac{3\pm \sqrt{9-4\cdot 2} }{2}= \frac{3\pm \sqrt{9-8} }{2}= \frac{3\pm1}{2}\\\\ x_1=\frac{3-1}{2} =\boxed{1}\\\\ x_2=\frac{3+1}{2} =\boxed{2}\\\\ \text{Functia atasata ecuatiei are semnul lui a in afara radacinilor si }\\ \text{semn opus intre radacini.}\\\\ \Longrightarrow~~~\boxed{\bf x\in (-\infty,~1)~\bigcup~(2,~+\infty)}[/tex]
