Putting values and finding the answer:
So, the expression is:
and 2730 different ways are possible.
Answer:
(x+8)(x^2-3)
Step-by-step explanation:
First you need to factor out the greatest common factor from each group.
x^2(x+8) - 3(x+8)
Factor the polynomial by factoring out the greatest common factor, x+8.
(

<h3>Conner work is correct. Jana work is wrong</h3>
<em><u>Solution:</u></em>
<em><u>Given that,</u></em>
<em><u>Conner and Jana are multiplying:</u></em>
Given Conner's work is:
We have to check if this work is correct
Yes, Conner work is correct
From given,
Use the following law of exponent
Therefore,
<em><u>Given Jana's work is:</u></em>
This is incorrect
The powers of same base has to be added. But here, powers are multiplied which is wrong
