Answer:
56
Step-by-step explanation:
Use the Order of Operations:
[tex](9 - 2)^{2} - [ {2}^{2} - {3}^{2}] + 2 = {7}^{2} - [4 - 9] + 2 = \\ \\ 49 - -5 + 2 = 49 + 5 + 2 = 56[/tex]
According to the Order of Operations, you evaluate everything on grouping symbols, then the exponents [indices, roots, etcetera], then Division & Multiplication from left to right, then finally, Subtraction & Addition from right to left [or left to right as long as you know what you are doing correctly].
