Multiply term-by-term:
(-4x - 5)(-x^2 - x + 4)
= (-4x)(-x^2) + (-4x)(-x) + (-4x)(4) + (-5)(-x^2) + (-5)(-x) + (-5)(4)
= 4x^3 + 4x^2 - 16x + 5x^2 + 5x - 20
= 4x^3 + 9x^2 - 11x - 20.
(-4x - 5)(-x^2 - x + 4)
= (-4x)(-x^2) + (-4x)(-x) + (-4x)(4) + (-5)(-x^2) + (-5)(-x) + (-5)(4)
= 4x^3 + 4x^2 - 16x + 5x^2 + 5x - 20
= 4x^3 + 9x^2 - 11x - 20.
