To find the sum of two polynomials, we simply combine like terms.
(4x3 − 2x − 9) + (2x3 + 5x + 3)
= (4x3 + 2x3) + (-2x + 5x) + (-9 + 3)
= 6x3 + 3x - 6
Therefore, the sum of the polynomials (4x3 − 2x − 9) and (2x3 + 5x + 3) is 6x3 + 3x - 6.
(4x3 − 2x − 9) + (2x3 + 5x + 3)
= (4x3 + 2x3) + (-2x + 5x) + (-9 + 3)
= 6x3 + 3x - 6
Therefore, the sum of the polynomials (4x3 − 2x − 9) and (2x3 + 5x + 3) is 6x3 + 3x - 6.
