Question 53860This question is from textbook Algebra 1 An Incremental Development
: This is more of a proceedural question.
My daughters teacher has taught them that -3^2=-9 while -(3^2)=9
And it states in the text on page 83 section 17.B this is the case.
I have been always taught that two negatives equal a positive.
Is this "new" math? Or am I mis-remembering
Thank You for any help you may provide

You may have typed in the problem wrong, but:
-3%5E2+=+-%283%2A3%29 = -9 This is correct.
-%283%5E2%29+=+-%283%2A3%29 = -9 ...not 9 as you show it.
Perhaps you meant to write:
%28-3%29%5E2+=+%28-3%29%28-3%29 = 9
