Rearrange like terms in this polynomial so like terms are next to each other 3-6x+4x^2+3x-6x^2-4

4x^2 - 6x^2   -6x + 3x    +3 - 4

Step-by-step explanation:

The terms here involve x^0, x, x^2.

Write the x^2 terms first:  4x^2 - 6x^2;

then write the x terms:  -6x + 3x; and

then write the constants:  3 - 4

and so we have, in descending powers of x,

4x^2 - 6x^2   -6x + 3x    +3 - 4
