Not sure if I'm applying the formula correctly. I'm trying to find the deflection in a cantilever beam that is loaded by a uniformly-distributed load. The formula is:

$$v=- \frac{wx^2}{24EI}(x^2+6L^2-4Lx) $$

Where:

$$v =Deflection\\ x=Distance\ from\ wall\\w=3\quad kN/m\\E=200\quad GPa\\I=986e6\quad mm^4\\L=10.5$$

So for x=10.5 I'm getting:
$$v=- \frac{3000(10.5)^2}{24*200e9*986e6}(10.5^2+6*10.5^2-4*10.5*10.5) $$

$$v=-2.31e-14$$
