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

expand

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

x^{3} + x^{2} (- 7 + 1) + x (- 7 - 2) + 27

Solution steps

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

Expand

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

= (x^{2} + x - 2) (x - 7)

Distribute parentheses

= x^{2} x + x^{2} (- 7) + xx + x (- 7) - 2 x - 2 (- 7)

Simplify

x^{2} x + x^{2} (- 7) + xx + x (- 7) - 2 x - 2 (- 7) : x^{3} + x^{2} (- 7 + 1) + x (- 7 - 2) + 27

= x^{3} + x^{2} (- 7 + 1) + x (- 7 - 2) + 27

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

(\frac{8}{x - 10} + 4 (100 - x)) (x - 10)

(x cos (θ) + y)^{2} - x^{2} sin^{2} (θ)

\frac{\partial}{\partial x} ((y) (2 x - 3 y)^{3})

e^{2 x} (e^{x} + 1)
