3x%5E2-4x-3+.....use quadratic formula

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ ...note that a=3, b=-4 and c=-3

x+=+%28-%28-4%29+%2B-+sqrt%28+%28-4%29%5E2-4%2A3%2A%28-3%29+%29%29%2F%282%2A3%29+

x+=+%284+%2B-+sqrt%2816%2B36%29%29%2F6+

x+=+%284+%2B-+sqrt%2852%29%29%2F6+

x+=+%284+%2B-+sqrt%284%2A13%29%29%2F6+

x+=+%284+%2B-+2%2Asqrt%2813%29%29%2F6+

x+=+cross%284%292%2Fcross%286+%293%2B-+cross%282%29%2Asqrt%2813%29%2Fcross%286%293+

x+=+2%2F3%2B-+sqrt%2813%29%2F3+

x+=+%282%2B-+sqrt%2813%29%29%2F3+
