Explicación paso a paso:
Numeral 1:
= 2 ( 2x² - 4x⁴ + 2x - 6 )
= 4x² - 8x⁴ + 4x - 12
Numeral 2:
= 5 ( 2x² + 4x - 2 )
= 10x² + 20x - 10
Numeral 3:
= 2x² ( - 3x³ + 2x² - 6x + 4 )
= - 6x⁵ + 4x⁴ - 12x³ + 8x²
Numeral 4:
= 4b ( a² - 3ab + 5b²c )
= 4a²b - 12ab² + 20b³c
Numeral 5:
= ( 2x - 4 ) ( 6x² - 4x + 3 )
= 2x ( 6x² - 4x + 3 ) = 12x³ - 8x² + 6x
= - 4 ( 6x² - 4x + 3 ) = - 24x² + 16x - 12
= 12x³ - 8x² - 24x² + 6x + 16x - 12
= 12x³ - 32x² + 22x - 12
Numeral 6:
= ( m - n² ) ( am - an - 3 )
= m ( am - an - 3 ) = am² - amn - 3m
= - n² ( am - an - 3 ) = - amn² + an³ + 3n²
= am² - amn - 3m - amn² + an³ + 3n²
= an³ + am² - amn² + 3n² - amn - 3m

= an³ + am² - amn² + 3n² - amn - 3m
