Question

why x3 +2x-2+3x-5 is not a polynomial​

Answer 1

Answer:

Step by Step Solution:



Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "x2"   was replaced by   "x^2".  1 more similar replacement(s).

STEP1:Equation at the end of step 1

(((x3) - 2x2) - 3x) - 5

STEP2:Checking for a perfect cube

 2.1    x3-2x2-3x-5  is not a perfect cube

Trying to factor by pulling out :

 2.2      Factoring:  x3-2x2-3x-5 

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  -3x-5 

Group 2:  x3-2x2 

Pull out from each group separately :

Group 1:   (3x+5) • (-1)

Group 2:   (x-2) • (x2)

Answer 2

______________________

ANSWER :

We know that a polynomial is a mathematical expression of one or more algebraic terms each of which consists of a constant multiplied by one or more variables raised to a non-negative integral power (whole number).

❌Not a polynomial because a term has a negative exponent

✔️Therefore, is not a polynomial
