Simplifying 3x2+7x+9+7x2+9x+83x^2 + 7x + 9 + 7x^2 + 9x + 8

To simplify the algebraic expression 3x2+7x+9+7x2+9x+83x^2 + 7x + 9 + 7x^2 + 9x + 8, apply the procedure for combining like terms. First, identify the matching parts: the x2x^2-terms are 3x23x^2 and 7x27x^2, the xx-terms are 7x7x and 9x9x, and the constants are 99 and 88. Second, combine each group by adding their coefficients. The sum of the x2x^2-terms provides 10x210x^2, the xx-terms provide 16x16x, and the constants sum to 1717. The resulting simplified algebraic expression is 10x2+16x+1710x^2 + 16x + 17.
