$$\frac { 49 } { 2 } [ 2 ( 1 ) + 48 ] - \frac { x } { 2 } [ 2 ( 1 ) + ( x - 1 ) ( 1 ) ]$$

Aromātai

$$\frac{\left(49-x\right)\left(x+50\right)}{2}$$

Ngā Hipanga Rongoā Poto

Whakareatia te 2 ki te 1, ka 2.

$$\frac{49}{2}\left(2+48\right)-\frac{x}{2}\left(2\times 1+\left(x-1\right)\times 1\right)$$

Tāpirihia te 2 ki te 48, ka 50.

$$\frac{49}{2}\times 50-\frac{x}{2}\left(2\times 1+\left(x-1\right)\times 1\right)$$

Tuhia te \frac{49}{2}\times 50 hei hautanga kotahi.

$$\frac{49\times 50}{2}-\frac{x}{2}\left(2\times 1+\left(x-1\right)\times 1\right)$$

Whakareatia te 49 ki te 50, ka 2450.

$$\frac{2450}{2}-\frac{x}{2}\left(2\times 1+\left(x-1\right)\times 1\right)$$

Whakawehea te 2450 ki te 2, kia riro ko 1225.

$$1225-\frac{x}{2}\left(2\times 1+\left(x-1\right)\times 1\right)$$

Whakareatia te 2 ki te 1, ka 2.

$$1225-\frac{x}{2}\left(2+\left(x-1\right)\times 1\right)$$

Whakamahia te āhuatanga tohatoha hei whakarea te x-1 ki te 1.

$$1225-\frac{x}{2}\left(2+x-1\right)$$

Tangohia te 1 i te 2, ka 1.

$$1225-\frac{x}{2}\left(1+x\right)$$

Tuhia te \frac{x}{2}\left(1+x\right) hei hautanga kotahi.

$$1225-\frac{x\left(1+x\right)}{2}$$

Whakamahia te āhuatanga tohatoha hei whakarea te x ki te 1+x.

$$1225-\frac{x+x^{2}}{2}$$

Hei tāpiri, hei tango kīanga rānei, me whakaroha ērā kia rite ā rātou tauraro. Whakareatia 1225 ki te \frac{2}{2}.

$$\frac{1225\times 2}{2}-\frac{x+x^{2}}{2}$$

Tā te mea he rite te tauraro o \frac{1225\times 2}{2} me \frac{x+x^{2}}{2}, me tango rāua mā te tango i ō raua taurunga.

$$\frac{1225\times 2-\left(x+x^{2}\right)}{2}$$

Mahia ngā whakarea i roto o 1225\times 2-\left(x+x^{2}\right).

$$\frac{2450-x-x^{2}}{2}$$

Whakaroha
