Factoring Practice 1 - Visualizing Algebra

• 0:00 - 0:05
We want to find factors of 10 that sum to negative 7. Well, the two factors must
• 0:05 - 0:10
be negative 2 and negative 5. We can rewrite the middle term using minus 2x and
• 0:10 - 0:15
minus 5x, from these factors. Then, we do our factoring by grouping and our
• 0:15 - 0:19
final answer is x minus 5 times x minus 2. This stuff right here is the
• 0:19 - 0:23
trickiest part. We need to factor out a negative 5 from both of these terms. If
• 0:23 - 0:28
I factor out a negative 5 from positive 10, I'm left with negative 2. Remember
• 0:28 - 0:32
that you can check your work by distributing. This allows us to be sure that
• 0:32 - 0:37
we've done factoring by grouping correctly. Moving this way would be factoring,
• 0:37 - 0:41
so if we distribute, we would be undoing that process. Nice work with your
• 0:41 - 0:45
negative numbers and your factoring if you got that one correct.
