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

expand

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

x^{2} + 5 + 4 x

Solution steps

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

Apply FOIL method

(x - (- 2 + i)) (x - (- 2 - i)) : x^{2} + 5 + 4 x

= x^{2} + 5 + 4 x

(\frac{6}{s ^{3}} - \frac{1}{s + 1}) (1 + \frac{1}{s - 1})

- \frac{40 ( - 34 x ^{4} - 343 x ^{2} - 208 )}{( x ^{2} - 16 ) ^{11}}

\frac{4 ( 3 x ^{2} ( 3 y ^{2} + 1 ) ^{2} - 24 x ^{6} y )}{( 3 y ^{2} + 1 ) ^{3}}

10 (5 - 5)

\frac{d}{d x} ((y) (sin (x) + x^{2}))
