Step-by-step explanation:

1-

[tex](9 - 2) ^{2} - (2 ^{2} - 3 ^{2} ) + 2[/tex]

calculate the powers behind the brackets from left to right

2-

[tex](49) ^ - (4 - 9 ) + 2[/tex]

Calculate the powers (a power squared means the number times itself so 2 squared equals 4)

3-

[tex]49 - - 5+2[/tex]

Calculate the sum ( minus minus equals plus so for example 4- -5= 4+5=9)

4- 49+5+2= 56

Answer: 56

Step-by-step explanation:

First we have to do whats in the parenthesis/ brackets, so lets rewrite the equation after we solve them.

(7)^2 - [4-9] + 2

We can simplify this even further

49 - [-5] + 2

54 + 2

56
