To find the zeros we need to let k(x)=0 so we have

So now we only care about the numerator. By this identity the denominator can be any number while the numerator is zero and the whole equation will be zero. So we can basically say:

Now we can solve for x by adding x to both sides

So our zero is
Notice the graph has an x-intercept of (4,0)
