(-2+i)(3-6i)

Answer 1

(-2+I)(3-6i)
-2i + -6i = 12i

Answer 2

15i

Explanation:

(-2+i)(3-6i)

Use the FOIL method then combine the real and imaginary parts of the expression.

(-2+i)(3-6i)

-2 (-3-6i) + i (3-6i)

-2 * 3 - 2 (-6i) + i (3-6i)

-2 * 3 - 2 (-6i) + i * 3 + i (-6i)

-6 + 12i + 3i + 6

0 + 12i + 3i

12i + 3i

15i
