Find an invertible matrix P and a matrix C of the form(a -b b a) such that the matrix A = (2 -37 1 4) has the form A = PCP^-1. The eigenvalues of A are 3 + 6 and 3 - 6 with corresponding eigenvectors (6 + i i) and (6 - i i). A The matrices P and C are.
B. There is no matrix C of the form [a -b b a] and no invertible matrix P such that A = PCP^-1

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.
