Відповідь:

-10х+12b-30xb-25x²+36b²+30bx

Пояснення:

это одновременно и просто ответ, и пошаговое

IraPipyka228: спасибо
y5dvbqdz57: А почему не скоротил -30xb и +30xb
Rottenapple: там значения разные, bx и xb
Rottenapple: bx = b * x, xb = x * b ; тоесть мы не можем сократить, посмотри внимательнее, там 30хб и 30бх
Rottenapple: хотя стой, может быть и да
Rottenapple: по идеи можно? я не уверен
Rottenapple: ну всё равно спасибо, буду знать))
