Question

Add (x^3 -2x^2+4) + (2x^3+x^2-2) express in standard form​

Answer 1

3x^3-x^2+0x+2

Explanation:

add both the equations then you will get

3x^3-x^2+2

but in the standard form there should be an x^1 term or x term since there is no term like that we write it as 0x

so the equation will be

3x^3-x^2+0x+2
