Whakaoti mō A
A=4x^{2}+4x-1
Whakaoti mō x (complex solution)
x=\frac{\sqrt{A+2}-1}{2}
x=\frac{-\sqrt{A+2}-1}{2}
Whakaoti mō x
x=\frac{\sqrt{A+2}-1}{2}
x=\frac{-\sqrt{A+2}-1}{2}\text{, }A\geq -2

Kua tāruatia ki te papatopenga
A=4x^{2}+x-3+3x+2
Whakamahia te āhuatanga tuaritanga hei whakarea te 4x-3 ki te x+1 ka whakakotahi i ngā kupu rite.
A=4x^{2}+4x-3+2
Pahekotia te x me 3x, ka 4x.
A=4x^{2}+4x-1
Tāpirihia te -3 ki te 2, ka -1.
