Is it a multiple choice question? If so, would you list the choices?

(3a+12)(a+4)^2-(3a+12)/(a^2-25)(a+3.5)^2-0.25(a^2-25)

@jameel.saeed you lost me with all those numbers .-. @Projects those are the choices

Okay well let's work this out step-by-step. (3a+12(a+4)^4 equals?
Projects

(3a+12)(a+4)^4 **

3*(a+4)^5

You remember PEMDAS?|dw:1433343689511:dw|

yes i can recall that

Okay, good well let's through and do this now. (4a+16)^2 - (3a+12) 4a + 3a equals 7a so now, (7a+16)^2 - (3a+12) 16 + 12 equals 28 (7a+28)^2 (35a)^2 (1225a)

so it would be the second one right?

Good work @projects

Now for the other half you got (1225a) / (a^2-25)(a+3.5)^2-0.25(a^2-25) (1225a) / (a^2-25)(a+3.5)^2 Whenever you see a "blank" variable with any raised power, there's a 1 in front of it so, (1225a) / (1a^2-25)(a+3.5)^2-0.25(a^2-25) (1225a) / (2a-25)(a+3.5)^2-0.25(a^2-25) (1225a) / (2a-25)(a+3.5)^2 (1225a) / (2a-21.5)^2 (1225a) / (-19.5a)^2 (1225a) / (380.25a) Thanks @jameel.saeed lol trying my best, lol

(1225a) / (380.25a)-0.25(a^2-25) You think you could do this one @Armadillo ??
