Adding Polynomials Calculator will find the sum of polynomials 3x^2+3x-1+9x^2+4x+3 i.e. 12 x^2 + 7 x + 2 along with a detailed explanation on how to approach.

**Ex: ** x^5+x^5+1+x^5+x^3+x (or) x^5+3x^5+1+x^6+x^3+x (or) x^3+x^5+1+x^3+x^3+x

The given Expression is 3x^2+3x-1+9x^2+4x+3

After grouping similar terms we get 3 x^2 + 9 x^2 + 3 x + 4 x - 1 + 3

After combining similar terms we get 4 x + 9 x^2 + 3 x^2 + 3 x - 1 + 3

x has similar terms 4 x,3 x

x^2 has similar terms 9 x^2,3 x^2

By adding all the similar terms we get 12 x^2 + 7 x + 2
