Find the factors for
Solution:
Consider the given equation above
The first and
the last terms are both perfect squares. The middle term is twice the
product of the square roots of first and last terms. Let's check the
middle term as follows
Since the
middle term is exactly the same as the computation above, then the given
trinomial is a perfect trinomial square. If the middle term is
negative, then the square root of the last term must be negative.
Therefore, the factors are
Therefore, the factors are

Find the factors completely for
Solution:
Consider the given equation above
Take out their common factor, we have
Since the two grouped terms are the difference of two squares, then we need to factor the two grouped terms as follows
Therefore, the factors are
