Let p; (t)=5+? pz(t) = t - 4t?, P3(t) = 4 +t-21° Complete parts (a) and (b) below.
B. The matrix A is invertible because it is row equivalent to 13 and therefore the row reduced Theorem
C. The matrix A forms a basis for R by the Invertible Matrix Theorem because all square ma
D. The matrix A is invertible because it is row equivalent to Iz and therefore the null space of Theorem
