Answer:

x - x + 3x³+ x² + 12

Step-by-step explanation:

( x² + 3 ) ( x³ - x² + 4 )

Multiply the second parentheses by each term from the first parentheses

x² ( x³ - x² + 4 ) + 3 ( x³ - x² + 4 )

Distribute x through the parentheses

x - x + 4x² + 3 ( x³ - x² + 4 )

Distribute 3 through the parentheses

x - x + 4x² + 3x³ - 3x² + 12

Collect like terms

x - x + x² + 3x³ + 12

Use the commutative property to reorder the terms

x - x + 3x³ + x² + 12

Hope this helps..
