expand (x-2)(x-7)(x+1)

expand

(x - 2) (x - 7) (x + 1)

x^{3} - 8 x^{2} + 5 x + 14

Solution steps

(x - 2) (x - 7) (x + 1)

Expand

(x - 2) (x - 7) (x + 1) : (x^{2} - 9 x + 14) (x + 1)

= (x^{2} - 9 x + 14) (x + 1)

Distribute parentheses

= x^{2} x + x^{2} \cdot 1 - 9 xx - 9 x \cdot 1 + 14 x + 14 \cdot 1

Simplify

x^{2} x + x^{2} \cdot 1 - 9 xx - 9 x \cdot 1 + 14 x + 14 \cdot 1 : x^{3} - 8 x^{2} + 5 x + 14

= x^{3} - 8 x^{2} + 5 x + 14

27 t^{2} sin (6 t - 60)

\frac{\partial}{\partial x} (3 e^{\frac{x}{y}})

y = \frac{6}{x}, (1, \frac{6}{1})

\frac{d}{d x} (\frac{cos ( x )}{x})

(2 x y^{2} - 3) d x + (2 x^{2} y + 4) d y = 0
