How would you solve the expressions 2+3i and 2-3i where I is an imaginary number? (i=√-1)
How would you solve the expressions 2+3i and 2-3i where I is an imaginary number? (i=√-1)
Not sure where to go from t^2=-49 I am aware of how to use "i"
when a real number and an imaginary number added together equals 0, does both the real number and the real part of the imaginary number have to equal 0?
It is a problem from my book and I dont know how to do it.
I need step by step examples please.
Do you use a different version of FOIL? Do you just multiply 8x4x(-9)? or do you multiply 8iX4i which equals 32 but then mutliply it by -1 because i^2=-1 so you'd have -32, and then multiply...
please help me to solve for the x and y value or help me by telling on hoe to start solving it.
"i" representing the square root of negative 1
