expand d(7cos(x)+2e^x)

expand

d (7 cos (x) + 2 e^{x})

7 d cos (x) + 2 d e^{x}

Solution steps

d (7 cos (x) + 2 e^{x})

Apply the distributive law:

a (b + c) = ab + a c

a = d, b = 7 cos (x), c = 2 e^{x}

= d \cdot 7 cos (x) + d \cdot 2 e^{x}

= 7 d cos (x) + 2 d e^{x}

\frac{2 x - 16}{( x + 2 ) ( x - 2 )}

A (5, - 9)

- 8 (11 + c = 0)

5 (x + h) + 2

x (x^{2} - 2 x + 2)^{2}
