umm, yes - use the distributive property.
(3√5 + 2)(4√-12 - 1)
(3√5 + 2)(8√-3 - 1)
(3√5)(8√-3) + (3√5)(-1) + (2)(8√-3) + (2)(-1)
24√-15 - 3√5 + 16√-3 - 2
How would I simplify (3 sqrt -5 + 2)(4 sqrt -12 – 1)?
I think that I would have to use the distributive property, but does anyone know the steps to solve this problem?

Thank you! Would the end answer be 18?
NO
How could you possibly equate all those square roots and imaginary numbers to 18?
Although I do see I made a typo. I missed the -5.
(3√-5 + 2)(4√-12 - 1)
(3√-5 + 2)(8√-3 - 1)
(3√-5)(8√-3) + (3√-5)(-1) + (2)(8√-3) + (2)(-1)
24√15 - 3√-5 + 16√-3 - 2
so why do you think the answer is 18?
