What is the simplest form of this expression? -x^3(5x+1)+4x^4

Fantom [35]

Answer:

-x^3*(x + 1)

Step-by-step explanation:

Perform the indicated multiplication and then write out all the terms in descending order by powers of x:

-x^3(5x+1)+4x^4 = -5x^4 - x^3 + 4x^4

= -x^4 - x^3, or = -x^3*(x + 1)
