(5x-3)(4x+5) the last step you have to look at the two terms that you are adding together the 4x(5x-3) and the 5(5x-3) and see what is similar. well the whole bracket is the same the 5x-3 so factor that out and collect the other leftover terms so the 4x and the +5 and thats what goes in the second bracket
You have to make the denominTors even, in this. Case it is 30. So you mutiply the 4 by 3 because you mutiply true 10 by 3 to get 30. So that fraction is now 12/30. Then mutiply the 2 by 2 because the 15 gets multiplied by 2 to get 30. So your equation is now 12/30 - 4/30. And you solve that to make 8/30. Simplify it to get 4/15. 4/15 is the answer. Hope this helps.
