Final answer:
To expand the expression (x²-4x-4)(3x²+x-1), use the distributive property and combine like terms if necessary. The expanded form is 3x⁴ - 11x³ -13x² + 9x + 4.
Step-by-step explanation:
To expand the expression (x²-4x-4)(3x²+x-1), we can use the distributive property. Multiply each term in the first expression (x²-4x-4) by each term in the second expression (3x²+x-1). Then, combine like terms if necessary.
The expanded form of the expression is 3x⁴ - 11x³ -13x² + 9x + 4.
