(3 + 2i) + (-4 + 6i)
Get rid of the parenthesis.
3 + 2i - 4 + 6i
Note how we got rid of the (+) sign in +(-4). We do this because a negative times a positive is always going to be a negative.
Combine like terms.
(2i + 6i) + (3 - 4)
Simplify.
8i - 1
~Hope I helped!~
The answer too 2 plus 2 is 4 because if you have 2 finger and add 2 more up it will be 4
Answer:
(-∞, -4] or [5, ∞)
Step-by-step explanation:
Because the solutions for x can also be equal to -4 and 5, brackets are used.
And because the solutions for x can be any number less than -4 or any number greater than 5, -∞ and ∞ are used respectively.
