Whakaoti i te (4a^{2}+b^2+a-5c+7)+(c^2-5+a-3b^2-6a^2)

$$( 4 a ^ { 2 } + b ^ { 2 } + a - 5 c + 7 ) + ( c ^ { 2 } - 5 + a - 3 b ^ { 2 } - 6 a ^ { 2 } )$$

Aromātai

$$2-5c+c^{2}-2b^{2}+2a-2a^{2}$$

Ngā Upane Otinga

Tangohia te 5 i te 7, ka 2.

$$4a^{2}+b^{2}+a-5c+2+c^{2}+a-3b^{2}-6a^{2}$$

Pahekotia te a me a, ka 2a.

$$4a^{2}+b^{2}+2a-5c+2+c^{2}-3b^{2}-6a^{2}$$

Pahekotia te b^{2} me -3b^{2}, ka -2b^{2}.

$$4a^{2}-2b^{2}+2a-5c+2+c^{2}-6a^{2}$$

Pahekotia te 4a^{2} me -6a^{2}, ka -2a^{2}.

$$-2a^{2}-2b^{2}+2a-5c+2+c^{2}$$

Kimi Pārōnaki e ai ki a
