Simplify the following expression:
Salsk061 [2.6K]

Simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.

<h3>What is an expression?</h3>

It is defined as the combination of constants and variables with mathematical operators.

The options are:

A) -x⁴ - 2x - x + 2

B) -x⁴ - 2x³ + 2x + 5

C) -2x³ + 1

D) -x - 2x² + 2x + 5

We have an expression:

= (x + 3) - [(x + 2)(x³ - 1)]

\rm =x+3-\left(x+2\right)\left(x^3-1\right)

\rm =x+3-x^4+x-2x^3+2

\rm =-x^4-2x^3+2x+3+2

\rm =-x^4-2x^3+2x+5

Thus, simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.
