Question

Let P2 be the vector space of all polynomials of degree 2 or less, and let H be the subspace spanned by x - 10x^2 + 4, 11x^2 + 8x - 8 and 3 - (6x^2 + x). a. The dimension of the subspace H is 3. b. Is {x - 10x^2 + 4, 11x^2 + 8x - 8, 3 - (6x^2 + x)} a basis for P2? not a basis for P_2 Be sure you can explain and justify your answer. c. A basis for the subspace H is { 11x^2+8x-8,-6x^2-x+3 }. Enter a polynomial or a comma separated list of polynomials. Note: In order to get credit for this problem all answers must be correct.

Step 1

To do this, we need to determine if the given polynomials are linearly independent or not. Let's consider the following linear combination: c1(10x^2 + 4) + c2(11x^2 + 8x - 8) + c3(3(-6x^2 + x)) = 0 Expanding and combining like terms, we get: (10c1 + 11c2 - Show more…
