\left(3x-5y\right)\left(x+3y\right)
Kimihia he tauwehe o te āhua kx^{m}+n, e wehea ai e kx^{m} te huatahi me te pū nui rawa 3x^{2}, e wehea hoki e n te tauwehe pūmau -15y^{2}. Ko tētahi tauwehe pērā ko 3x-5y. Whakatauwehea te pūrau mā te whakawehe ki tēnei tauwehe.
3x^{2}+4xy-15y^{2}
Pahekotia te 9xy me -5xy, ka 4xy.
