Which expression is the simplest form of 2x^3 - x^2 + 3 (x^3 - 4x^2)
jolli1 [7]

The simplest form of the given expression is 5x^3-5x^2.

We have given that

2x^3 - x^2 + 3 (x^3 - 4x^2)

We have to determine the simplest form of the given expression.

<h3>What is the distributive property?</h3>

The distributive property of binary operations generalizes the distributive law, which asserts that equality is always true in algebra. elementary.

Use the distributive property we get,

2x^3 - x^2 + 3 (x^3 - 4x^2)\\=2x^3 - x^2 +3x^3-12x^2\\

Add like terms we get,

Therefore we get,

=5x^3-5x^2

Therefore the simplest form of the given expression is 5x^3-5x^2.
