simplify (2s+6i-4m)+(7s-2i-2m)

simplify

(2 s + 6 i - 4 m) + (7 s - 2 i - 2 m)

(9 s - 6 m) + 4 i

Solution steps

(2 s + 6 i - 4 m) + (7 s - 2 i - 2 m)

Rewrite

2 s + 6 i - 4 m

in standard complex form:

(2 s - 4 m) + 6 i

Rewrite

7 s - 2 i - 2 m

in standard complex form:

(7 s - 2 m) - 2 i

= (2 s - 4 m) + 6 i + (7 s - 2 m) - 2 i

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

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

= ((2 s - 4 m) + (7 s - 2 m)) + (6 - 2) i

Simplify

((2 s - 4 m) + (7 s - 2 m)) + (6 - 2) i : (9 s - 6 m) + 4 i

= (9 s - 6 m) + 4 i

- 0.75 - 0.4

(7 + 3 i)^{2}

\frac{( \frac{x}{2} - 1 )}{x - 2}

2 a^{2} - 5 a - 12

(\frac{2 x}{y})^{3}
