## Simplify Rational Expressions Practice 7 - Visualizing Algebra

• 0:00 - 0:05
Our numerator is a difference of two perfect squares. So we can factor it as 2x
• 0:05 - 0:11
plus 5y times 2x minus 5y. This denominator isn't identical to one of our
• 0:11 - 0:16
factors, but it is an opposite polynomial for this factor. We can see that the
• 0:16 - 0:21
2xs are opposite in sign and the 5ys are also opposite in sign. So these two
• 0:21 - 0:27
factors simplify to be negative 1 and were left with negative 1. Times 2x plus
• 0:27 - 0:33
5y. We can distribute our negative 1 to get our answer, negative 2x minus 5y.
• 0:33 - 0:36
Fantastic work if you got that expression.
