Answer 1

A)
(x² - x + 3)x = x³ - x² + 3x

B)
(x² + 3x - 2)x² = x^4 + 3x³ - 2x²

C)
xy(x² + xy - y²)x = x²y(x² + xy - y²) = x^4y + x³y² - x²y³

D)
- x²y³(4 - 3xy² + 2x²y³) = - 4x²y³ + 3x³y^5 - 2x^4y^6

E)
(6 - 3x³y + 9x²y³)/3
3(2 - x³y + 3x²y³)/3
2 - x³y + 3x²y³

F)
2x^m(x^m - 2x^(m+1))
2x^2m - 4x^(2m+1)

G)
(2x³)(5x³)
10x^6

H)
2(12x³)(4x)
(24x³)(4x)
96x^4

I)
35(2x²y³z)
70x²y³z

J)
4(5x²y³z)(2y²z²)
(20x²y³z)(2y²z²)
40x²y^5z³

K)
(18x³y²z^5)(6x³yz²)
108x^6y³z^7

L)
( - 2x³)( - 5x)( - 3x²)
(10x^4)( - 3x²)
- 30x^6
