Answer:
Option (b) is correct.
The expression is equivalent, but the term is not completely factored.
Step-by-step explanation:
Given : a student factors to
We have to choose the correct statement about from the given options.
Given is factored to
Consider
Using algebraic identity,
comparing and b = 4, we have,
Thus, the factorization is equivalent but we can simplify it further also, as
Using algebraic identity,
Thus,
Can be written as
Thus, the expression is equivalent, but the term is not completely factored.
Option (b) is correct.
Answer:
C) 
Step-by-step explanation:
Given Equations:
A) 
B) 
In order to eliminate 
we need to multiply 
to equation B and add it to A.
Multiplying to B.
⇒ 
⇒ 
⇒ 
Adding it equation A.
+ 
We get 
Thus is eliminated.
So, the expression used to eliminate is:
