Which of the following quartic functions has x=-1 and x=-2 as its only two real zeros?

x^4-3x^3+3x^2-3x+2
x^4+3x^3+3x^2-3x-2
x^4+3x^3+3x^2+3x+2
x^4-3x^3-3x^2+3x+2

x^4 - 3x^3 + 3x^2 - 3x + 2

x = 1 and x = 2

x = -0.5147 and x = 0.8516

x = -2 and x = -1

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

well what you have to do is divide 84 by 6 so theanswer

step-by-step explanation:

84 divided by 6 = 14
