derivative of

F (x) = 7 x^{6} (x^{4} - 7 x)

7 (10 x^{9} - 49 x^{6})

Solution steps

\frac{d}{d x} (7 x^{6} (x^{4} - 7 x))

Take the constant out:

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

= 7 \frac{d}{d x} (x^{6} (x^{4} - 7 x))

Apply the Product Rule:

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

f = x^{6}, g = x^{4} - 7 x

= 7 (\frac{d}{d x} (x^{6}) (x^{4} - 7 x) + \frac{d}{d x} (x^{4} - 7 x) x^{6})

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

\frac{d}{d x} (x^{4} - 7 x) = 4 x^{3} - 7

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

Expand

6 x^{5} (x^{4} - 7 x) + (4 x^{3} - 7) x^{6} : 10 x^{9} - 49 x^{6}

= 7 (10 x^{9} - 49 x^{6})
