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

expand

(x - 1) (x + 2 i) (x - 2 i)

x^{3} + 4 x - x^{2} - 4

Solution steps

(x - 1) (x + 2 i) (x - 2 i)

Expand

(x - 1) (x + 2 i) (x - 2 i) : (x - 1) (x^{2} + 4)

= (x - 1) (x^{2} + 4)

Apply FOIL method

(x - 1) (x^{2} + 4) : x^{3} + 4 x - x^{2} - 4

= x^{3} + 4 x - x^{2} - 4

(\frac{1}{12}) (t) (L + \frac{t}{2} + \frac{R}{2})^{3}

\frac{110 ( ln ( x ) - 2 )}{x}

2 (x^{3} sin (x^{3}) + cos (x^{3}) - 1)

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

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