Whakaoti i te x^2+8b+155=0

$$x ^ { 2 } + 8 b + 155 = 0$$

Whakaoti mō b

$$b=\frac{-x^{2}-155}{8}$$

Ngā Upane mō te Whakaoti Whārite Rārangi

Tangohia te x^{2} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.

$$8b+155=-x^{2}$$

Tangohia te 155 mai i ngā taha e rua.

$$8b=-x^{2}-155$$

Whakawehea ngā taha e rua ki te 8.

$$\frac{8b}{8}=\frac{-x^{2}-155}{8}$$

Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.

$$b=\frac{-x^{2}-155}{8}$$

Whakaoti mō x (complex solution)

$$x=-\sqrt{-8b-155}$$

$$x=\sqrt{-8b-155}$$

Whakaoti mō x

$$x=\sqrt{-8b-155}$$

$$x=-\sqrt{-8b-155}\text{, }b\leq -\frac{155}{8}$$
