In set of prime numbers P 2, find the change-of-coordinates matrix from the basis Upper B equals StartSet 1 minus 3 t plus t squared comma 2 minus 5 t plus 3 t squared comma 3 t plus 4 t squared EndSet to the standard basis Upper C equals StartSet 1 comma t comma t squared EndSet. Then find the B-coordinate vector for negative 2 plus 7 t.
