derivative of f(x)=(6x+7)(7x-8)

Solution

derivative of

f (x) = (6 x + 7) (7 x - 8)

Solution

84 x + 1

Solution steps

\frac{d}{d x} ((6 x + 7) (7 x - 8))

Apply the Product Rule:

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

f = 6 x + 7, g = 7 x - 8

= \frac{d}{d x} (6 x + 7) (7 x - 8) + \frac{d}{d x} (7 x - 8) (6 x + 7)

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

\frac{d}{d x} (7 x - 8) = 7

= 6 (7 x - 8) + 7 (6 x + 7)

Simplify

6 (7 x - 8) + 7 (6 x + 7) : 84 x + 1

= 84 x + 1

\frac{d y}{d x} = \frac{2 x}{1 + 2 y}, y (2) = 1

(2x)/y dx-(x^2)/(y^2)dy=0
