Question 208173: I am not sure how to solve this:
2d^2 + 3d^2 - 4e^2 - 5e^2
I know (2d^2 + 3d^2) = 5d^2
but is the next part of the equation
-(4e^2 - 5e^2) = -1e^2 or
+(-4e^2 - 5e^2) = -9e^2
Can you please help?
Thank you!!!!

2d^2 + 3d^2 - 4e^2 - 5e^2
I know (2d^2 + 3d^2) = 5d^2
but is the next part of the equation
-(4e^2 - 5e^2) = -1e^2 or
+(-4e^2 - 5e^2) = -9e^2
