linear algebra problem

If anyone could explain how the following problem is done, it would be greatly appreciated!

For each of the two cases below, find the dimension of V by using an appropriate method to create a basis.

a) V = span({x^4 - x^3 + 2x^2, 2x^4 + x - 5, 2x^3 - 4x^2 + x - 4, 6, x^2 - 1})

(In this one E means epsilon)
b) V = {p E P_6 | p = ax^6 - bx^5 + ax^4 - cx^3 + (a+b+c)x^2 - (a - c)x + (3a - 2b - 16c), for real numbers a, b, and c
