expand (0.72+0,92i)*(0.08-0.54i)

expand

(0.72 + 0, 92 i) \cdot (0.08 - 0.54 i)

0.72 \cdot 0.08 - 0.72 \cdot 0.54 i + 0, 92 \cdot 0.08 i - 0, 92 \cdot 0.54 ii

Solution steps

(0.72 + 0, 92 i) (0.08 - 0.54 i)

= (0.72 + 0 \cdot 92 i,) (0.08 - 0.54 i)

Apply FOIL method:

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

a = 0.72, b = 0, 92 i, c = 0.08, d = - 0.54 i

= 0.72 \cdot 0.08 + 0.72 (- 0.54 i) + 0, 92 i 0.08 + 0, 92 i (- 0.54 i)

Apply minus-plus rules

+ (- a) = - a

= 0.72 \cdot 0.08 - 0.72 \cdot 0.54 i + 0, 92 \cdot 0.08 i - 0, 92 \cdot 0.54 ii

\frac{1}{( a + x ) ( x + b )}

(x + d x) + 5 (x^{2} - 1)
