Expert Solution

Answer to Problem 1E

The complete statements are,

How many terms does this polynomial have?  3 

List the terms:  2x5,6x4,4x3 

Which factor is common to each term?  2x3

Factor the polynomial: 2x5+6x4+4x3=

  2x3(x2+3x+2)

Explanation of Solution

Given information:

The polynomial 2x5+6x4+4x3 .

Consider the provided polynomial 2x5+6x4+4x3 .

Number of terms in a polynomial is the number of terms separated by mathematical operations.

Here, the terms are separated by addition sign between three expressions, so, the given polynomial contains 3 terms.

The terms in the polynomial are the ones which are separated by addition sign between them,

So, the polynomial contains the following terms,  2x5,6x4,4x3  .

The greatest common factor to these terms is 2x3  .

Recall that to factorize a polynomial, take the common factor out and simplify it.

So, 2x5+6x4+4x3 will be factorized as,

  2x5+6x4+4x3=2x3(x2+3x+2)

Thus, the complete statements are,

How many terms does this polynomial have?  3 

List the terms:  2x5,6x4,4x3 

Which factor is common to each term?  2x3

Factor the polynomial: 2x5+6x4+4x3=

  2x3(x2+3x+2)
