In the given expression, calculate as indicated. Express your answer as a single polynomial in standard form. (7x^5 + 9x^3 + 3x) + (4x^4 - 6x^3 + 4x^2)

Solution

(7x⁵ + 9x³ + 3x) + (4x⁴ - 6x³ + 4x²) = 7x⁵ + 9x³ + 3x + 4x⁴ - 6x³ + 4x²                                                       

                                                        = 7x⁵ + 4x⁴ + (9x³ - 6x³)+ 4x² + 3x                                                       

                                                        = 7x⁵ + 4x⁴ + 3x³ + 4x² + 3x
