2(3 + 9x) - 2x
= 6 + 9x - 2x <----------------mistake right here
= 6 + 7x
Correct:
Expanding by using distributive property
2(3 + 9x) - 2x
= 2* 3 + 2 * 9x - 2x
= 6 + 18x - 2x
= 6 + 16x
1. The answer is already in its simplest form.
3. 3i + i is equal to 4i.
5. Combining like terms results in -5 - 9i.
