%282x%5E%28-4%29y%5E%28-4%29%29%28-7x%5E4y%5E%28-2%29%29

Multiply the coefficients 2 by -7 and get -14

Add the exponents of x-4 and x4 and get x0, which is 1.

Add the exponents of y-4 and y-2 and get y-6, which is 1%5E%22%22%2Fy%5E6.

So now we have-14%2A1%2Aexpr%281%5E%22%22%2Fy%5E6%29

which simplifies to -14%5E%22%22%2Fy%5E6
