Beyond the Answer
To find the value of
that satisfies the equation
, we first simplify the right-hand side.
Starting with the right-hand side:
Expanding
:
Substituting back into the equation:
Now, we can rearrange the right-hand side:
Now we need to match the coefficients of the left-hand side
. This gives us:
- The coefficients of
: Both sides have . - The coefficients of
: .
To solve for
, we need the right-hand side to be equal for certain constants, but we don’t have enough information about
provided in the question. If we assume a typical value like
:
Thus, if
,
. So the answer is
.
So the correct option is:
B. -1.
