What are the possible rational zeros of f(x) = x4 + 2x3 − 3x2 − 4x + 12?

The answer is plus or minus 1,2,3,4,6,12, those are the possible rational xeros and we can find this if we take the leading coefficient 1 from x^4 and the constant 12

We now could use our p/q

P would be your 12 and your q would be 1

Now find the factors of 12 and 1

p/q= 12/1= 1,2,3,4,6,12 /1 (all plus or minus)

possible rational zeros 1,2,3,4,6,12 (all plus or minus) :)

step-by-step explanation:

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
