Determine whether each statement makes sense or does not make sense, and explain your reasoning. Although $20{x}^{3}$ appears in both $20{x}^{3}+8{x}^{2}\text{}{\textstyle \phantom{\rule{1em}{0ex}}}\text{and}{\textstyle \phantom{\rule{1em}{0ex}}}\text{}20{x}^{3}+10x$ , I’ll need to factor $20{x}^{3}$ in different ways to obtain each polynomial’s factorization?

Step 1

Determine whether each statement makes sense or does not make sense, and explain your reasoning. Although$20{x}^{3}$ appears in both $20{x}^{3}+8{x}^{2}\text{}{\textstyle \phantom{\rule{1em}{0ex}}}\text{and}{\textstyle \phantom{\rule{1em}{0ex}}}\text{}20{x}^{3}+10x$ , I’ll need to factor $20{x}^{3}$ in different ways to obtain each polynomial’s factorization?

Step 2

We are given two expressions:

$20{x}^{3}+8{x}^{2}$

and$20{x}^{3}+10x$

if we factorize them,

$20{x}^{3}+8{x}^{2}=4{x}^{2}(5x+2)$

and$20{x}^{3}+10x=10x(2{x}^{2}+1)$

We see that factorization depends on each term of the expression, so although both expressions contain one common term, because of the other term both have different ways.

Step 1

Given:

$20{x}^{3}+8{x}^{2}{\textstyle \phantom{\rule{1em}{0ex}}}\text{and}{\textstyle \phantom{\rule{1em}{0ex}}}20{x}^{3}+10x$

Step 2

Yes! statement makes sense

$20{x}^{3}+8{x}^{2}$

Break terms:

$=2x\times 2x\times 5x+2x\times 2x\times 2$

Take common out:

$=2x\times 2x(5x+2)$

$=4{x}^{2}(5x+2)$

Step 3

$20{x}^{3}+10x$

Take common out:

$=10x(2{x}^{2}+1)$

Given:

Step 2

Yes! statement makes sense

Break terms:

Take common out:
