To solve this equation, we first need to calculate the values of 27.9^2 and 29.7^2:
27.9^2 = 779.4129.7^2 = 882.09
Now we substitute these values back into the equation:
779.41 - 882.09 / 27.9 + 29.7
= -102.68 / 57.6
= -1.78
Therefore, 27.9^2 - 29.7^2 / 27.9 + 29.7 = -1.78.
To solve this equation, we first need to calculate the values of 27.9^2 and 29.7^2:

29.7^2 = 882.09
Now we substitute these values back into the equation:
779.41 - 882.09 / 27.9 + 29.7
= -102.68 / 57.6
= -1.78
Therefore, 27.9^2 - 29.7^2 / 27.9 + 29.7 = -1.78.
