Question: Using the expression from Step 1, combine variable terms by adding the coefficients and add the constant terms. (4x2 + 8x2) + (9x + 3x)

Using the expression from Step 1, combine variable terms by adding the coefficients and add the constant terms. (4x2 + 8x2) + (9x + 3x) + (5 + 1.5) = (4 + 8)x2 + (9 + 3)x + (5 + 1.5) = x2 x + So, the expression 4x2 + 5 9x + 1.5 + 3x + 8x2 simplifies to
