Problem 3: Consider the set of polynomials {-1+3t – 2t“, 4 – 10t + 3t², 4 – 8t – 2t“} . Let p,(t) = – 1+ 3t – 21², p2(t) = 4 – 10t + 31², and p3(t) = 4 – 8t – 212. Let H = span {p,(t), P2(t), P3(t)}, which is a subset of P2. (a) Is the polynomial 10 – 12t – 25t2 in H? Answer this question directly without the use of the coordinate mapping. WhatI mean by directly is: can you find a, b, and, c such that ap (t) + bp2(t) +cp3(t) = 10 – 12t – 25t2. If you answer yes, write 10 – 12t – 25t2 as a linear combination of p,(t), P2(t), and, p3(t). If no, make sure your work makes clear why.
