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
slope = -
calculate the slope m using the gradient formula
m= (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (- 3, 6)
m = =
= -
