Factor-by-grouping yields:

-x³ - 4x + x^4 + 2x² - 8 = 0
-x(x² + 4) + (x² - 2)(x² + 4) = 0
(x² + 4)(x² - 2 - x) = 0
(x² + 4)(x² - x - 2) = 0
(x² + 4)(x - 2)(x + 1) = 0

Finally, by zero-product property:

x² + 4 = 0 and x - 2 = 0 and x + 1 = 0
x² = -4 and x = {2,-1}
x = ±v-4 and x = {-1,2}
x = {-1, 2, ±2i}

I hope this helps!

36n^2 - 30n - 8

Or if you want an actual answer, you take each term, multiply the exponent by the constant and then subtract one from the exponent. So 12n^3 is 3x12n^3-1 which equals 36n^2 and so on

I just told you how sweet pea. I can also teach you some manners and such too
