Consider the following polynomials in â₃:

q(x) = 2x³+3x²â2x+1
r(x) = 6x³+8x²âx+2
u(x) = x³âx²+7xâ2

For each of the following polynomials, determine whether it is in span{q, r, u}. If so, express it as a linear combination of the polynomials above.
Use, e.g., q rather than q(x) to represent the polynomials in your linear combination.

p1(x) = 4x³+6x²â4x+2 [select answer]
p2(x) = -5x³+x²â8x-8 [select answer]
p3(x) = -9x³â14x²+7xâ5 [select answer]
