Find the correct sum of the polynomials (4x3 − 2x − 9) + (2x3 + 5x + 3)
Algebraic expressions that have variables and coefficients are called polynomials.
Answer: The sum of the polynomials (4x3 − 2x − 9) and (2x3 + 5x + 3) is 6x3 + 3x − 6.
Let's add the given polynomials.
We add polynomials by adding the coefficients of the same power.
