(3 - 5 i) + (6 + 9 i)

9 + 4 i

Solution steps

(3 - 5 i) + (6 + 9 i)

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

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

= (3 + 6) + (- 5 + 9) i

Simplify

(3 + 6) + (- 5 + 9) i : 9 + 4 i

= 9 + 4 i

\frac{9 - 2 i}{i - 5}

(x - 1) (x - 2) (x + 3) (x + 4)

\frac{\frac{n + 3}{2 n - 6}}{\frac{n + 3}{3 n - 9}}

(x + 1)^{2} - 9

a - (b + a) + (- a + b) - (- a + 2 b)
