Answer:
+ 8x³ + 12x² - 16x + 4
Step-by-step explanation:
Given
[(x² + 4x) - 2 ]² ← simplify contents of bracket
= (x² + 4x - 2)² = (x² + 4x - 2)(x² + 4x - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
x²(x² + 4x - 2) + 4x(x² + 4x - 2) - 2(x² + 4x - 2) ← distribute parenthesis
= + 4x³ - 2x² + 4x³ + 16x² - 8x - 2x² - 8x + 4 ← collect like terms
= + 8x³ + 12x² - 16x + 4
The equation showing the relationship between w and t is
From the table, we have the following points:
(0,0) and (1,4)
Start by calculating the slope (m)
So, we have:
Simplify the numerator and the denominator
Divide 4 by 1
The equation is then calculated as:
This gives
Simplify
Hence, the equation is
