Whakaoti mō y
y=-\left(x+2\right)\left(x+5\right)
Whakaoti mō x (complex solution)
x=\frac{\sqrt{9-4y}-7}{2}
x=\frac{-\sqrt{9-4y}-7}{2}
Whakaoti mō x
x=\frac{\sqrt{9-4y}-7}{2}
x=\frac{-\sqrt{9-4y}-7}{2}\text{, }y\leq \frac{9}{4}
Graph
Tohaina
Kua tāruatia ki te papatopenga
y=\left(-x-5\right)\left(x+2\right)
Hei kimi i te tauaro o x+5, kimihia te tauaro o ia taurangi.
y=-x^{2}-7x-10
Whakamahia te āhuatanga tuaritanga hei whakarea te -x-5 ki te x+2 ka whakakotahi i ngā kupu rite.
Ngā Tauira
