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

expand

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

x^{2} - 6 x + 10

Solution steps

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

Distribute parentheses

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

Simplify

xx + x (- 3) + x i - 3 x - 3 (- 3) - 3 i - i x - i (- 3) - ii : x^{2} - 6 x + 10

= x^{2} - 6 x + 10

(cos (x) cos (y) - cot (x)) d x - sin (x) sin (y) d y

\frac{5 ( x + 2 )}{6}

(a + b - a - b)^{2}

\frac{1}{3} + \frac{2}{9} (1.2 - 1)
