1. ## PEMDAS Help

Can I get some help on this problem, in detail please?

7 { 6 [ 8*( T - 6 ) +12 ] + 2* ( T + 11 ) } ^2
7 { 6 [ 8t - 48 + 12 ] + 2t + 22} ^ 2
7 { 6 [ 8t - 60 ] + 2t + 22} ^ 2
7 { 48t - 360 + 2t + 22} ^ 2
7 { 50t - 338 } ^ 2

Now, at this point do i do 50t ^ 2 - 338^2 (which is 114244)?
Then 7 { 50t^2 - 114244}
Then 350T^2 - 799708?
If thats not correct can someone help me fix this?
Then

2. 7 { 6 [ 8t - 60 ] + 2t + 22} ^ 2
This line has an error in it. It's the third line down from the top.

3. $\displaystyle (a-b)^2 = a^2-2ab+b^2 \neq a^2-b^2$

4. you told me in the problem
7 { 6 [ 8*( T - 6 ) +12 ] + 2* ( T + 11 ) } ^2
7 { 6 [ 8t - 48 + 12 ] + 2t + 22} ^ 2
7 { 6 [ 8t - 60 ] + 2t + 22} ^ 2
7 { 48t - 360 + 2t + 22} ^ 2
7 { 50t - 338 } ^ 2

7 { 6 [ 8t - 60 ] + 2t + 22} ^ 2
this line has an error in it?
what should I have done differentely?

5. What's -48 + 12?
