6. Приведите многочлен к стандартному виду: \( 2 x \cdot 3 x+7 x^{2}-x \cdot 3+8 x x-x \cdot 12 x \). 7. Приведите многочлен \( (-a b) \cdot a+9 b \cdot a b+(-1)^{2004} \cdot b \cdot(-a)^{4}-a \cdot(-3 b)^{2}-a^{4} b \) к стандартному виду и найдите его значение при \( a=-3, b=5 \).

Quick Answer
6. Многочлен \( 2 x \cdot 3 x + 7 x^{2} - x \cdot 3 + 8 x x - x \cdot 12 x \) в стандартном виде: \( 9x^{2} - 3x \).
7. Многочлен \( (-a b) \cdot a + 9 b \cdot a b + (-1)^{2004} \cdot b \cdot (-a)^{4} - a \cdot (-3 b)^{2} - a^{4} b \) в стандартном виде: \( -a^{2} b \). Значение при \( a = -3, b = 5 \): \(-45\).
