Whakaoti i te 4R_{1}+7R_{2}5R_{1}-3R_{2}2R_{2}-R_{1}

$$4 R _ { 1 } + 7 R _ { 2 } 5 R _ { 1 } - 3 R _ { 2 } 2 R _ { 2 } - R _ { 1 }$$

Aromātai

$$35R_{1}R_{2}+3R_{1}-6R_{2}^{2}$$

Ngā Upane Otinga

Whakareatia te R_{2} ki te R_{2}, ka R_{2}^{2}.

$$4R_{1}+7R_{2}\times 5R_{1}-3R_{2}^{2}\times 2-R_{1}$$

Whakareatia te 7 ki te 5, ka 35.

$$4R_{1}+35R_{2}R_{1}-3R_{2}^{2}\times 2-R_{1}$$

Whakareatia te 3 ki te 2, ka 6.

$$4R_{1}+35R_{2}R_{1}-6R_{2}^{2}-R_{1}$$

Pahekotia te 4R_{1} me -R_{1}, ka 3R_{1}.

$$3R_{1}+35R_{2}R_{1}-6R_{2}^{2}$$

Kimi Pārōnaki e ai ki R_1

$$35R_{2}+3$$
