Question

Preform the indicated operation: -[5 - 2(3^2 - 2)]. Please show work.

Thank you! :)

Answer 1

start with the innermost set of brackets

3^2 = 9

so its 9 - 2 = 7

then its

\[-1 \times [5 - 2 \times (7)] \]

inside the square brackets you need to do 2 x 7

then the subtraction...

lastly multiply the answer by -1

hope it helps

Answer 2

Where'd you get the -1?

And yeah it helps, thanks :)

Answer 3

the negative sign outside the brackets is the same as saying -1 times everything in the square brackets

Answer 4
