Whakaoti i te {left(-1/2-3right)}^2-(-1/2)(5*(-1/2)-6)

$${ \left(- \frac{ 1 }{ 2 } -3 \right) }^{ 2 } -(- \frac{ 1 }{ 2 } )(5 \times (- \frac{ 1 }{ 2 } )-6)$$

Ngā Upane Otinga

Tangohia te 3 i te -\frac{1}{2}, ka -\frac{7}{2}.

$$\left(-\frac{7}{2}\right)^{2}-\left(-\frac{1}{2}\left(5\left(-\frac{1}{2}\right)-6\right)\right)$$

Tātaihia te -\frac{7}{2} mā te pū o 2, kia riro ko \frac{49}{4}.

$$\frac{49}{4}-\left(-\frac{1}{2}\left(5\left(-\frac{1}{2}\right)-6\right)\right)$$

Whakareatia te 5 ki te -\frac{1}{2}, ka -\frac{5}{2}.

$$\frac{49}{4}-\left(-\frac{1}{2}\left(-\frac{5}{2}-6\right)\right)$$

Tangohia te 6 i te -\frac{5}{2}, ka -\frac{17}{2}.

$$\frac{49}{4}-\left(-\frac{1}{2}\left(-\frac{17}{2}\right)\right)$$

Whakareatia te -\frac{1}{2} ki te -\frac{17}{2}, ka \frac{17}{4}.

$$\frac{49}{4}-\frac{17}{4}$$

Tangohia te \frac{17}{4} i te \frac{49}{4}, ka 8.

$$8$$
