What is the sum of the polynomials?<br> (7x^3– 4x^2) + (2x^3 +3x)

DaniilM [7]

Answer:

sum of the polynomials is $9 x^{3} - 4 x^{2} +3x$

Step-by-step explanation:

Given polynomial is (7 x^3– 4 x^2) + (2 x^3 +3 x)

adding x^3 terms, now we get

$(7+2)x^3-4 x^2+3 x$

$9 x^{3} - 4 x^2 +3 x$

Therefore the sum of given polynomial is

$9 x^3-4 x^2+3 x$
