Question

Tara and Curtis are simplifying [4(10)-3^2]+6(4). is either of them correct? Explain your reasoning. Why wouldnt the -3^2 be positive 9? my parents said that it cant be used as a negative in the situation or whatever, but how would i be able to tell on future quizzes or tests

Answer 1

Simplifying the given expression, it is found that Curtis is correct.

How to simplify the expression?

The expression to be simplified is given by:

[4(10) - 3²] + 6(4)

The non-related operations can be solved first, hence:

[4(10) - 3²] + 6(4) = [40 - 9] + 24

For the square, we have to consider that:

• For -x², the negative is not part of the square, hence the result is negative, as - x*x = -x².

• For (-x)², the negative is part of the square, hence the result is positive, as (-x)*(-x) = x².

The first bullet point is the reason that -3² = 9. Then, the simplified expression is completed as follows:

[40 - 9] + 24 = 31 + 24 = 55.

Which means that Curtis is correct.
