Sagot :
Simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.
What is an expression?
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)]
[tex]\rm =x+3-\left(x+2\right)\left(x^3-1\right)[/tex]
[tex]\rm =x+3-x^4+x-2x^3+2[/tex]
[tex]\rm =-x^4-2x^3+2x+3+2[/tex]
[tex]\rm =-x^4-2x^3+2x+5[/tex]
Thus, simplification form of the provided expression is -x⁴-2x³+2x+5 option (B) is correct.
