Simplify the following expression. (-2+i)(3-6i)

-9i
15i
-12 +15i
-12-9i

15i

Step-by-step 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

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.
