expand (2+4i,)(-6-3i,)

expand

(2 + 4 i,) (- 6 - 3 i,)

- 2 \cdot 6 - 2 \cdot 3 i, - 4 i, 6 - 4 i, 3 i,

Solution steps

(2 + 4 i,) (- 6 - 3 i,)

Apply FOIL method:

(a + b) (c + d) = a c + a d + b c + b d

a = 2, b = 4 i,, c = - 6, d = - 3 i,

= 2 (- 6) + 2 (- 3 i,) + 4 i, (- 6) + 4 i, (- 3 i,)

Apply minus-plus rules

+ (- a) = - a

= - 2 \cdot 6 - 2 \cdot 3 i, - 4 i, 6 - 4 i, 3 i,

B + (1 - B) e^{- k t}

5 (- 4 x + y - 7 = 0)

\frac{16}{16} - \frac{6}{16}

1.2538 \frac{( 1 + 0.16 s ) ( 1 + 0.16 s )}{s}

- 2 (y + x \frac{d}{d x} ((y) (y)))
