Σx^{2}=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x^{2}Σ=-x
He hanga arowhānui tō te whārite.
\frac{x^{2}Σ}{x^{2}}=-\frac{x}{x^{2}}
Whakawehea ngā taha e rua ki te x^{2}.
Σ=-\frac{x}{x^{2}}
Mā te whakawehe ki te x^{2} ka wetekia te whakareanga ki te x^{2}.
Σ=-\frac{1}{x}
Whakawehe -x ki te x^{2}.
Σx^{2}=-x
Tangohia te x mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x^{2}Σ=-x
He hanga arowhānui tō te whārite.
\frac{x^{2}Σ}{x^{2}}=-\frac{x}{x^{2}}
Whakawehea ngā taha e rua ki te x^{2}.
Σ=-\frac{x}{x^{2}}
Mā te whakawehe ki te x^{2} ka wetekia te whakareanga ki te x^{2}.
Σ=-\frac{1}{x}
Whakawehe -x ki te x^{2}.
