derivative of f(x)=x^3(3x-5)^2

Solution

derivative of

f (x) = x^{3} (3 x - 5)^{2}

Solution

45 x^{4} - 120 x^{3} + 75 x^{2}

Solution steps

\frac{d}{d x} (x^{3} (3 x - 5)^{2})

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x^{3}, g = (3 x - 5)^{2}

= \frac{d}{d x} (x^{3}) (3 x - 5)^{2} + \frac{d}{d x} ((3 x - 5)^{2}) x^{3}

\frac{d}{d x} (x^{3}) = 3 x^{2}

\frac{d}{d x} ((3 x - 5)^{2}) = 6 (3 x - 5)

= 3 x^{2} (3 x - 5)^{2} + 6 (3 x - 5) x^{3}

Simplify

3 x^{2} (3 x - 5)^{2} + 6 (3 x - 5) x^{3} : 45 x^{4} - 120 x^{3} + 75 x^{2}

= 45 x^{4} - 120 x^{3} + 75 x^{2}
