Add. (8r^2 + 8r + 3) + (5r + 6) ______

Write Expressions: Write down the expressions to be added. (8r^2 + 8r + 3) + (5r + 6) Here, we are adding two polynomials together. Remove Parentheses: Remove any parentheses and combine like terms. 8r^2 + 8r + 3 + 5r + 6 Since there are no subtraction signs or negative coefficients outside the parentheses, we can simply drop the parentheses and combine like terms. Combine Like Terms: Combine the like terms. 8r^2 + (8r + 5r) + (3 + 6) Here, we group the r terms and the constant terms. Perform Addition: Perform the addition of like terms. 8r^2 + 13r + 9 We add the coefficients of the like terms: 8r + 5r = 13r and 3 + 6 = 9.
