8x^{2}-6x-2>8x\left(x+5\right)
Whakamahia te āhuatanga tuaritanga hei whakarea te 4x+1 ki te 2x-2 ka whakakotahi i ngā kupu rite.
8x^{2}-6x-2>8x^{2}+40x
Whakamahia te āhuatanga tohatoha hei whakarea te 8x ki te x+5.
8x^{2}-6x-2-8x^{2}>40x
Tangohia te 8x^{2} mai i ngā taha e rua.
-6x-2>40x
Pahekotia te 8x^{2} me -8x^{2}, ka 0.
-6x-2-40x>0
Tangohia te 40x mai i ngā taha e rua.
-46x-2>0
Pahekotia te -6x me -40x, ka -46x.
-46x>2
Me tāpiri te 2 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
x<\frac{2}{-46}
Whakawehea ngā taha e rua ki te -46. I te mea he tōraro a -46, ka huri te ahunga koreōrite.
x<-\frac{1}{23}
Whakahekea te hautanga \frac{2}{-46} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
