To find the solution set to the equation
, we need to find the values of
that make the equation equal to zero.The equation is a product of two factors:
and
. For the equation to be equal to zero, at least one of the factors must be equal to zero.Let's consider the first factor,
. This factor is a perfect square, so it is always non-negative. The only way for it to be equal to zero is if
. Solving this equation, we get
.Now let's consider the second factor,
. This factor is a linear term, so it can be equal to zero if
.Therefore, the solution set to the equation is
.So, the correct answer is B)
.
