Question

sobre derivadas preciso de ajuda

Answer 1

1 - Regra da cadeia

3/2. ( 3-4x+3x²)¹/². (3-4x+3x²)'

3/2. (3-4x+3x²)¹/².(6x-4)'

simplifica

3. (3-4x+3x²)¹/². (3x-2)'

9x-6 . (3-4x+3x²)¹/²

2- Regra do quociente

f(x)= 5x² - 3x +2

f'(x)= 10x - 3

g(x)= 1-2x

g'(x)= -2

(1-2x).(10x-3) - (5x²-3x+2).(-2)

10x-3-20x²+6 - (-10x² + 6x -4)

10x - 3- 20x² +6 + 10x² - 6x +4

-10x² + 4x +7

------------------

( 1 - 2x ) ²
