T2 please

Working with Technology T1. Recall from Theorem 1.3.1 that a product Ax can be expressed as a linear combination of the column vectors of the matrix A in which the coefficients are the entries of x. Use matrix mul- tiplication to compute v = 6(8, –2, 1, –4) + 17(–3,9, 11, 6) – 9(13, –1,2, 4) T2. Use the idea in Exercise T1 and matrix multiplication to deter- mine whether the polynomial p = 1+x+x? +x³ is in the span of P = 8 – 2x + x² – 4x', p2 = -3+ 9x + 11x² + 6x³, P3 = 13 – x + 2x² + 4x³
