Answer:
The given expressions simplifies to tan (4x).
Step-by-step explanation:
Here, the given expression is : 
By TRIGONOMETRIC IDENTITY:

Putting this identity here, and taking A = 9 x, B = 5 x, we get

= tan(4x)
Hence, the given expressions simplifies to tan (4x).
56x² - 49x + 14 = 7(8x² - 7x +2)
_____
The greatest common factor of 56, 49, and 14 is 7.

<h3>What is a transformation of geometry?</h3>
A spatial transformation is each mapping of feature shapes to itself, and it maintains some spatial correlation between figures.
Reflection does not change the size and shape of the geometry.
