Best ResponseYou've already chosen the best response.1That's true! :) You need to regroup so you can do the subtraction. Distribute the subtraction to both the 2x and the 5,\[\large\rm (4x5)(2x+5)\]\[\large\rm 4x52x5\]Subtract like this instead,\[\large\rm 4x2x55\]

Best ResponseYou've already chosen the best response.1Woops! Notice the first 5 has a minus in front of it. Treat that not as subtraction, but as a (negative 5). So your really trying to figure out 55
