Algebra
5 raruraru e ōrite ana ki:
( x ^ { 2 } - y ^ { 2 } ) - [ ( x + y ) ( x - y ) ] + 3 x ^ { 2 }
Tohaina
Kua tāruatia ki te papatopenga
x^{2}-y^{2}-\left(x^{2}-y^{2}\right)+3x^{2}
Whakaarohia te \left(x+y\right)\left(x-y\right). Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
x^{2}-y^{2}-x^{2}+y^{2}+3x^{2}
Hei kimi i te tauaro o x^{2}-y^{2}, kimihia te tauaro o ia taurangi.
-y^{2}+y^{2}+3x^{2}
Pahekotia te x^{2} me -x^{2}, ka 0.
0+3x^{2}
Pahekotia te -y^{2} me y^{2}, ka 0.
3x^{2}
Ko te tau i tāpiria he kore ka hua koia tonu.
x^{2}-y^{2}-\left(x^{2}-y^{2}\right)+3x^{2}
Whakaarohia te \left(x+y\right)\left(x-y\right). Ka taea te whakareanga te panoni ki te rerekētanga o ngā pūrua mā te ture: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
x^{2}-y^{2}-x^{2}+y^{2}+3x^{2}
Hei kimi i te tauaro o x^{2}-y^{2}, kimihia te tauaro o ia taurangi.
-y^{2}+y^{2}+3x^{2}
Pahekotia te x^{2} me -x^{2}, ka 0.
0+3x^{2}
Pahekotia te -y^{2} me y^{2}, ka 0.
3x^{2}
Ko te tau i tāpiria he kore ka hua koia tonu.
