You're definitely getting closer!
Check the signs on the last two terms. When you expanded 1500(R + 250)^2 there was a "-" associated with the 1500. That must distribute over the whole thing when you distribute the 1500.Jimmy87 said:Finally we have:
250R^2 + 750,000R + 562500000 - 1500R^2 + 750,000R + 937500000
