Sophia did not complete her homework last week. She has forgotten how to add and subtract rational fraction below. Sophia was given the problem below as practice for a quiz. Your task is to help Sophia remember how to solve this problem.

a)Listing the steps to solve the problem. b)Show the work for each step.

Example

Step 1:

Step 2:
Helpp me and explain show your work
and if you try to send a document that does work

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
