The addition of the polynomials $2x^3+4x-6$ and $3x^3-8x+7$ in the proper location on the grid is $5x^3-4x+1$

How to find the addition of two polynomials is proper location on the grid ?

Polynomials addition in proper location means add the coefficient of same power of variable

So the addition of polynomials like this

$2x^3+4x-6+3x^3-8x+7$

$2x^3+3x^3=5x^3\\4x-8x=-4x\\-6+7=1$

The addition of the polynomials is $2x^3+4x-6+ 3x^3-8x+7=5x^3-4x+1$
