The first answer should have been= (1/2m)(1/2m) - (3/4n)(3/4n)which will eventually be (1/2m+3/4n)(1/2m-3/4n).

9/16 should equals to 3/4 instead of still staying as 9/16n.

9/16 does not = to (9/16)(9/16), it should have been (3/4)(3/4)

The first part of the question should have been=(1/2m)(1/2m)-(3/4n)(3/4n)=(1/2m+3/4n)(1/2m+3/4n)=(1/2m+3/4n)^2

9/16 n^2 is not (9/16 n)(9/16 n). it is (3/4 n)(3/4n)

9/16n^2 should have become (3/4n)(3/4n) instead of (9/16n)(9/16n)

9/16n^2≠ (9/16n)(9/16n)9/16n^2= (3/4n)(3/4n)

He forgot to sq-rt 9/16The 1st expression should be (1/2m)(1/2m)-(3/4n)(3/4n)= (1/2m)²-(3/4n)²Further simplify: (1/2m-3/4n)(1/2m+3/4n)

He did not square root 9/16(1/2m)(1/2m)-(3/4n)(3/4n) =(1/2m+3/4n)(1/2m-3/4n)

The person thought that 9/16 n^2 is the same as (9/16 n)(9/16 n) when it was supposed to be (3/4 n)(3/4 n).

The 9/16n^2 should be (3/4n)(3/4n) and not (9/16n)(9/16n) and so the final answer should be (1/2m+3/4n)(1/2m-3/4m)

He has forgot to square root 9/16 and so it shld be (3/4)(3/4)

Its is correct, except that it has not been simplified to its simplest form. The end result shuld look like (1/2m + 3/4n)(1/2 - 3/4n)

The first answer should have been

ReplyDelete= (1/2m)(1/2m) - (3/4n)(3/4n)

which will eventually be (1/2m+3/4n)(1/2m-3/4n).

ReplyDeleteThe first part of the question should have been

ReplyDelete=(1/2m)(1/2m)-(3/4n)(3/4n)

=(1/2m+3/4n)(1/2m+3/4n)

=(1/2m+3/4n)^2
