Question

perform the indicated operation. write the answer in the form (a + bi).
((2i)(3i)=)

Explanation:

Step1: Multiply the coefficients

$2\times3 = 6$

Step2: Multiply the imaginary units

$i\times i=i^{2}$
Since $i^{2}=- 1$, then $6\times i^{2}=6\times(-1)= - 6$. We can write it as $-6 + 0i$.

Answer:

$-6+0i$
