Question

simplify and expand (1+i)^2(3-4i)​

Answer 1

Solution:

=> (1 + i)² (3 - 4i)

=> (1 + i² + 2i) (3 - 4i)

=> (1 - 1 + 2i) (3 - 4i)

=> 2i (3 - 4i)

=> 6i - 8i²

=> 8 + 6i

Here, Real part is 8 and imaginary part is 6.

Extra information:

z = a + bi

Here z represents the complex number a represents the real part of the number and b represents the imaginary part of the number. i (called as iota) = √-1.
