derivative of

7 x^{5} (x^{3} - 6 x)

7 (8 x^{7} - 36 x^{5})

Solution steps

\frac{d}{d x} (7 x^{5} (x^{3} - 6 x))

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= 7 \frac{d}{d x} (x^{5} (x^{3} - 6 x))

Apply the Product Rule:

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

f = x^{5}, g = x^{3} - 6 x

= 7 (\frac{d}{d x} (x^{5}) (x^{3} - 6 x) + \frac{d}{d x} (x^{3} - 6 x) x^{5})

\frac{d}{d x} (x^{5}) = 5 x^{4}

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

= 7 (5 x^{4} (x^{3} - 6 x) + (3 x^{2} - 6) x^{5})

Expand

5 x^{4} (x^{3} - 6 x) + (3 x^{2} - 6) x^{5} : 8 x^{7} - 36 x^{5}

= 7 (8 x^{7} - 36 x^{5})
