Please factor -8.4x^3y^4 - 3.6x^2y^5 - 4.8x^4y^3
= 1.2x^2 y^3(7xy - 3y^2 - 4x^2y)
Hmmm.
-1.2x^2y^3(7xy + 3y^2 + 4x^2)
-1.2x^2y^3(x+y)(4x+3y)
To factor the expression -8.4x^3y^4 - 3.6x^2y^5 - 4.8x^4y^3, we can look for any common terms or factors among the terms, and then use the distributive property of multiplication to factor out those terms.
First, let's identify the common factors among the terms. In this expression, the common factors among the terms are x^2 and y^3. We can factor them out using the distributive property.
So, the factored expression will be:
-8.4x^3y^4 - 3.6x^2y^5 - 4.8x^4y^3
= (x^2y^3)(-8.4x - 3.6y^2 - 4.8x^2)
Therefore, the factored form of the expression -8.4x^3y^4 - 3.6x^2y^5 - 4.8x^4y^3 is (x^2y^3)(-8.4x - 3.6y^2 - 4.8x^2).
