First we find the measurement of dark dot .
ANd for that we have to use the formula of the angle formed by the intersection of chord .
Let the dark dot be t.
So we have
t and z are linear pair and sum of angles of linear pair =180 degree.
So we get
Answer:
8x² + 8
Step-by-step explanation:
Given
(x² + 3)² - (x² - 1)² ← expand both factors using FOIL
= + 6x² + 9 - (
- 2x² + 1) ← distribute by - 1
= + 6x² + 9 -
+ 2x² - 1 ← collect like terms
= 8x² + 8
