How do you find all zeros of this function fx equals 3x4 plus 10x3 plus 8x2 minus x minus 2?
I plotted it and found that it crosses the x-axis at x = -2, -1, then approx -0.77 and approx 0.434, so I factored (using long division) (x+2) and (x+1), to get 3x2 + x -1 as a factor. Using the quadratic formula gives:
(-1 - sqrt(13))/6 and (-1 + sqrt(13))/6
as the exact values for -0.77 & 0.434
