Ответ:

Многочлен  стандартноj виде - это многочлен, который представлен  в виде суммы одночленов стандартного вида, среди которых нет подобных одночленов.

4xy-3xy+2x^2=(4xy-3xy)+2x^2=2x^2+xy\\\\2b^2+7ab-9ab+6b^2-8b^2=(2b^2+6b^2-8b^2)+(7ab-9ab)=-2ab\\\\4\, n^2\cdot (-m)\, a\cdot m+2a^3\cdot 7a^9=-4\, a\, m^2n^2+14\, a^{12}
