(-3+2iroot48)(-5-4iroot12)<br> HELP PLEASE
alexira [117]

Answer:

-16 i sqrt(3) + 207

Step-by-step explanation:

Simplify the following:

(2 i sqrt(48) - 3) (-4 i sqrt(12) - 5)

sqrt(12) = sqrt(2^2×3) = 2 sqrt(3):

(2 i sqrt(48) - 3) (-4 i×2 sqrt(3) - 5)

-4×2 = -8:

(2 i sqrt(48) - 3) (-8 i sqrt(3) - 5)

Factor -1 from -8 i sqrt(3) - 5:

(2 i sqrt(48) - 3)×-(8 i sqrt(3) + 5)

sqrt(48) = sqrt(2^4×3) = 2^2 sqrt(3):

-(2 i×2^2 sqrt(3) - 3) (8 i sqrt(3) + 5)

2^2 = 4:

-(2 i×4 sqrt(3) - 3) (8 i sqrt(3) + 5)

2×4 = 8:

-(8 i sqrt(3) - 3) (8 i sqrt(3) + 5)

-(8 i sqrt(3) - 3) = -8 i sqrt(3) + 3:

-8 i sqrt(3) + 3 (8 i sqrt(3) + 5)

(-8 i sqrt(3) + 3) (8 i sqrt(3) + 5) = 3×5 + 3×8 i sqrt(3) + -8 i sqrt(3)×5 + -8 i sqrt(3)×8 i sqrt(3) = 15 + 24 i sqrt(3) - 40 i sqrt(3) + 192 = -16 i sqrt(3) + 207:

Answer:  -16 i sqrt(3) + 207
