Tohaina
Kua tāruatia ki te papatopenga
-30a+5P=-2^{a^{2}}
Tangohia te 2^{a^{2}} mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
5P=-2^{a^{2}}+30a
Me tāpiri te 30a ki ngā taha e rua.
5P=30a-2^{a^{2}}
He hanga arowhānui tō te whārite.
\frac{5P}{5}=\frac{30a-2^{a^{2}}}{5}
Whakawehea ngā taha e rua ki te 5.
P=\frac{30a-2^{a^{2}}}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
P=-\frac{2^{a^{2}}}{5}+6a
Whakawehe -2^{a^{2}}+30a ki te 5.
