Whakaoti i te (7x^{4}-5x^{5}+4x^{2}-7)+(x^3-3x^2-5+x)+(-3x^4+5-8x+2x^3)

$$( 7 x ^ { 4 } - 5 x ^ { 5 } + 4 x ^ { 2 } - 7 ) + ( x ^ { 3 } - 3 x ^ { 2 } - 5 + x ) + ( - 3 x ^ { 4 } + 5 - 8 x + 2 x ^ { 3 } )$$

Aromātai

$$-5x^{5}+4x^{4}+3x^{3}+x^{2}-7x-7$$

Ngā Upane Otinga

Pahekotia te 4x^{2} me -3x^{2}, ka x^{2}.

$$7x^{4}-5x^{5}+x^{2}-7+x^{3}-5+x-3x^{4}+5-8x+2x^{3}$$

Tangohia te 5 i te -7, ka -12.

$$7x^{4}-5x^{5}+x^{2}-12+x^{3}+x-3x^{4}+5-8x+2x^{3}$$

Pahekotia te 7x^{4} me -3x^{4}, ka 4x^{4}.

$$4x^{4}-5x^{5}+x^{2}-12+x^{3}+x+5-8x+2x^{3}$$

Tāpirihia te -12 ki te 5, ka -7.

$$4x^{4}-5x^{5}+x^{2}-7+x^{3}+x-8x+2x^{3}$$

Pahekotia te x me -8x, ka -7x.

$$4x^{4}-5x^{5}+x^{2}-7+x^{3}-7x+2x^{3}$$

Pahekotia te x^{3} me 2x^{3}, ka 3x^{3}.

$$4x^{4}-5x^{5}+x^{2}-7+3x^{3}-7x$$
