expand (4-x)ln(x+7)

expand

(4 - x) ln (x + 7)

4 ln (x + 7) - x ln (x + 7)

Solution steps

(4 - x) ln (x + 7)

= ln (x + 7) (4 - x)

Apply the distributive law:

a (b - c) = ab - a c

a = ln (x + 7), b = 4, c = x

= ln (x + 7) \cdot 4 - ln (x + 7) x

= 4 ln (x + 7) - x ln (x + 7)

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

(x - \frac{1}{x})^{12}

\frac{d}{d v} ((p) (p + \frac{4.1}{v ^{2}}) (v - 8.5))

(sin (a) + cos (b))^{2} + (cos (a) + sin (b))^{2}

(tan (x) + 1) (3 cot (x) - 1)
