Answer
Well first you need to remove parentheses by multiplying factors. Next
use exponent rules to remove parentheses in terms with exponents. Then
combine like terms by adding coefficients. Finally you just
combine the constants.
To complete the square you take the coefficient of the 'b' term (10), divide it by 2 (10/2), then square it (5^2 = 25). This is the number you add.
