expand (x-6/7)(x+2)(x+6)

expand

(x - \frac{6}{7}) (x + 2) (x + 6)

x^{3} + \frac{50 x ^{2}}{7} + \frac{36 x}{7} - \frac{72}{7}

Solution steps

(x - \frac{6}{7}) (x + 2) (x + 6)

Expand

(x - \frac{6}{7}) (x + 2) (x + 6) : (x^{2} + \frac{8 x}{7} - \frac{12}{7}) (x + 6)

= (x^{2} + \frac{8 x}{7} - \frac{12}{7}) (x + 6)

Distribute parentheses

= x^{2} x + x^{2} \cdot 6 + \frac{8 x}{7} x + \frac{8 x}{7} \cdot 6 - \frac{12}{7} x - \frac{12}{7} \cdot 6

Simplify

x^{2} x + x^{2} \cdot 6 + \frac{8 x}{7} x + \frac{8 x}{7} \cdot 6 - \frac{12}{7} x - \frac{12}{7} \cdot 6 : x^{3} + \frac{50 x ^{2}}{7} + \frac{36 x}{7} - \frac{72}{7}

= x^{3} + \frac{50 x ^{2}}{7} + \frac{36 x}{7} - \frac{72}{7}

\frac{h L ( xL b - L ^{2} + L P )}{( b ( L - x ) ( h - 1 ) )}

(15 cos (t) + 5 sin (t)) \cdot (5 cos (t) + 5 sin (t))

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

(x^{2} + 5 - 3) (x^{2} + 5 + 3)

lo g_{3} (x) (\frac{x ^{2}}{81 y ^{4}})
