expand (x-3+2i)(x-3-2i)

expand

(x - 3 + 2 i) (x - 3 - 2 i)

x^{2} - 6 x + 13

Solution steps

(x - 3 + 2 i) (x - 3 - 2 i)

Distribute parentheses

= xx + x (- 3) + x (- 2 i) - 3 x - 3 (- 3) - 3 (- 2 i) + 2 i x + 2 i (- 3) + 2 i (- 2 i)

Simplify

xx + x (- 3) + x (- 2 i) - 3 x - 3 (- 3) - 3 (- 2 i) + 2 i x + 2 i (- 3) + 2 i (- 2 i) : x^{2} - 6 x + 13

= x^{2} - 6 x + 13

\frac{2 x + 2}{( x - 1 ) ( x + 3 )}

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

\frac{- 40 x ^{2} - 11 x + 92}{( 4 x + 1 ) ( 5 x - 1 ) ( x - 10 )}

(2 - x)^{4}

\frac{1}{( 3 - 8 i \cdot x ) ^{5}}
