Whakaoti i te b^27-5x+2+3x=-4x+3+x

$$b ^ { 2 } 7 - 5 x + 2 + 3 x = - 4 x + 3 + x$$

Whakaoti mō x

$$x=1-7b^{2}$$

Ngā Upane Otinga

Pahekotia te -5x me 3x, ka -2x.

$$b^{2}\times 7-2x+2=-4x+3+x$$

Pahekotia te -4x me x, ka -3x.

$$b^{2}\times 7-2x+2=-3x+3$$

Me tāpiri te 3x ki ngā taha e rua.

$$b^{2}\times 7-2x+2+3x=3$$

Pahekotia te -2x me 3x, ka x.

$$b^{2}\times 7+x+2=3$$

Tangohia te b^{2}\times 7 mai i ngā taha e rua.

$$x+2=3-b^{2}\times 7$$

Tangohia te 2 mai i ngā taha e rua.

$$x=3-b^{2}\times 7-2$$

Whakareatia te -1 ki te 7, ka -7.

$$x=3-7b^{2}-2$$

Tangohia te 2 i te 3, ka 1.

$$x=1-7b^{2}$$

Whakaoti mō b (complex solution)

$$b=-\frac{\sqrt{7-7x}}{7}$$

$$b=\frac{\sqrt{7-7x}}{7}$$

Whakaoti mō b

$$b=\frac{\sqrt{7-7x}}{7}$$

$$b=-\frac{\sqrt{7-7x}}{7}\text{, }x\leq 1$$
