evaluate the expressions using the following values (-1^2+11^2)(11^2- -7^2)
2 answers
I do not dare because I bet you have typos. For example I would be surprised if -1^2 is not supposed to be (-1)^2.
I'll take a stab at it.
As written, it appears to be
(-1^2+11^2)(11^2- -7^2)
(-1+121)(121- -49)
(120)(170)

If we assume the usual carelessness with parentheses, per Damon, then we have
((-1)^2+11^2)(11^2- (-7)^2)
(1+121)(121-49)
(122)(72)

I can't believe you didn't try to work this out on your calculator.
Next time, show your work, and we can try to figure out what you might have meant. We're volunteers, not mind readers.
