simplify 3i(2+5i)+(6-7i)-(9+i)

Solution

simplify

3 i (2 + 5 i) + (6 - 7 i) - (9 + i)

Solution

- 18 - 2 i

Solution steps

3 i (2 + 5 i) + (6 - 7 i) - (9 + i)

Remove parentheses:

(a) = a

= 3 i (2 + 5 i) + 6 - 7 i - (9 + i)

3 i (2 + 5 i) = - 15 + 6 i

= (- 15 + 6 i) + 6 - 7 i - (9 + i)

Remove parentheses:

(- a) = - a

= - 15 + 6 i + 6 - 7 i - (9 + i)

- (9 + i) : - 9 - i

= - 15 + 6 i + 6 - 7 i - 9 - i

Simplify

- 15 + 6 i + 6 - 7 i - 9 - i : - 18 - 2 i

= - 18 - 2 i
