Polynomials in ascending/ descending order?

Question

Arrange the terms of each polynomial so that the powers of x are in ascending order.
20) 3a^2x^4+14a^2-10x^3+ax^2

18) -3+3x^3-x^2+4x

Arrange the terms of each polynomial so that the powers of x are in descending order.

26) 13-x^3y^3+x^2y^2+x

25) 2cx+32-c^3x^2+6x^3

These are two problems in each section i need help on , thanks

Answer 1

20) 3a^2x^4+14a^2-10x^3+ax^2



Just look at power of x for each term:



3a^2x^4 (power of x = 4)

14a^2 . .(power of x = 0)

-10x^3 . (power of x = 3)

ax^2 . . .(power of x = 2)



Now it's simply a matter of arranging these terms so that the respective powers of x

(4, 0, 3, 2) are in ascending order : (0, 2, 3, 4)



14a^2 + ax^2 - 10x^3 + 3a^2x^4



I really don't see what's so complicated about this.
