Combining Like Terms in 8a2+12a+1+3a25a+48a^2 + 12a + 1 + 3a^2 - 5a + 4

To simplify the expression 8a2+12a+1+3a25a+48a^2 + 12a + 1 + 3a^2 - 5a + 4, group and combine the like terms. First, identify the terms with the same variables and exponents: the a2a^2-terms (8a28a^2 and 3a23a^2), the aa-terms (12a12a and 5a-5a), and the constants (11 and 44). Adding their coefficients yields 8+3=118 + 3 = 11 for the a2a^2-terms, 125=712 - 5 = 7 for the aa-terms, and 1+4=51 + 4 = 5 for the constants. The fully simplified expression is 11a2+7a+511a^2 + 7a + 5.
