Very easy:
3x%5E2+-+8x+=+-2 Make a part c by adding 2 to both sides.
3x%5E2+-+8x+%2B+2+=+0 Since this doesn't factor, use the quadratic formula to solve.
%28-b%2B-sqrt%28b%5E2-4ac%29%29%2F2a where: a = 3, b = -8, and c = 2
x+=+%28-%28-8%29%2B-sqrt%28%28-8%29%5E2-4%2A3%2A2%29%29%2F%282%2A3%29
x+=+%288%2B-sqrt%2864-24%29%29%2F6
x+=+%284%2F3%29%2B-sqrt%2840%29%2F6
x+=+4%2F3%2B-sqrt%2810%29%2F3
