Option B : is the expression equivalent to
Explanation:
The given expression is
Rewriting the expression using the exponent rule,
Hence, we get,
Simplifying, we get,
Applying the rule,
Thus, we have,
Now, we shall determine from the options that which expression is equivalent to
Option A:
The expression is not equivalent to simplified expression
Thus, the expression is not equivalent to
Hence, Option A is not the correct answer.
Option B:
The expression is equivalent to the simplified expression
Thus, the expression is equivalent to
Hence, Option B is the correct answer.
Option C:
The expression is not equivalent to the simplified expression
Thus, the expression is not equivalent to
Hence, Option C is not the correct answer.
Option D:
The expression is not equivalent to the simplified expression
Thus, the expression is not equivalent to
Hence, Option D is not the correct answer.
Option A
is one way to determine the factors of
by grouping
<em><u>Solution:</u></em>
Factoring by grouping means that you will group terms with common factors before factoring
<em><u>Given expression is:</u></em>
Group the first two terms together and then the last two terms together.
We can see that is common in first two terms
And 3 is common in last two terms
Factor them out
Thus option A is correct
