Marcus and jeremy both evaluated the expression −52 + 3. marcus said the answer was −22. jeremy said the answer was 28. who is correct? explain the error in the other student’s work.

Marcus is correct. Jeremy squared -5 instead of 5. The negative is not within parentheses, so it is not squared.

You need to determine who is correct between Marcus and Jeremy

Jeremy is correct

Given:

-5² + 3

Marcus calculation:

-5² + 3

= -5 × - 5 + 3

= -25 + 3

= -22

He is wrong because he calculated -5² as -25 which is 25

So,

-25 + 3

= -22

Jeremy's calculation:

-5² + 3

= -5 × -5 + 3

= 25 + 3

= 28

Jeremy is correct

Note:

- × - = +

- × + = -
