expand (x-2i)(4-2i)

expand

(x - 2 i) (4 - 2 i)

(4 x - 4) + (- 2 x - 8) i

Solution steps

(x - 2 i) (4 - 2 i)

Apply FOIL method

(x - 2 i) (4 - 2 i) : 4 x - 2 x i - 8 i - 4

= 4 x - 2 x i - 8 i - 4

Rewrite in standard complex form:

(4 x - 4) + (- 2 x - 8) i

= (4 x - 4) + (- 2 x - 8) i

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

\frac{x ^{4} - 12 x}{( x ^{2} - 4 ) ^{2}}

18 sin^{9 x} (x) (ln (sin (x)) + x cot (x))

(x + 7) (x - 7)

e^{x} (cos (x) - sin (x))
