(16 - 9 i) - (2 - 9 i)

14

Solution steps

(16 - 9 i) - (2 - 9 i)

Group the real part and the imaginary part of the complex number

(a + bi) - (c + d i) = (a - c) + (b - d) i

= (16 - 2) + (- 9 - (- 9)) i

Simplify

(16 - 2) + (- 9 - (- 9)) i : 14

= 14

16 \cdot (\frac{2}{3})^{- 4}

(9 - x)^{2}

(- 5 + 10 i)^{2}

(8 x^{2} - 2 x + 1) - (3 x^{2} + 5 x - 8)

(- 2 - 6 i) - (- 2 - 4 i)
