Like any algebra equation, it can only be solved if it is set equal to something. Also, since there are 2 variables (a and d), you would need 2 equations to solve it. This can be simplified by grouping like terms (the ones with the same variable combinations) together. Start by grouping all of the d^ terms together, and add or subtract the numbers to get one number with the d^ variable. Next, group all of the ad terms together, again adding or subtracting the numbers as indicated by the signs. This way, it is at least simplified:
[d^ - 2d^ + 3d^] + [2ad + 8ad - 20ad]
which simplifies to [2d^] + [-10ad] which becomes 2d^ - 10ad

Hope that helps. Math is one of those subjects that the more you practice, the better you get. It works just like a sport, music, or even art.
