Several equations are given illustrating a suspected number pattern. Determine what the next equation would be,and verify that it is indeed a true statement. $2^{2}-1^{2}=2+1$ $3^{2}-2^{2}=3+2$ $4^{2}-3^{2}=4+3$ Select the correct choice below and fill in the answer box to complete your choice. (Type an equation, Do not simplify.) A. The next equation would be $\square $ , but it is a false statement. B. The next equation would be $\square $ , and it is a true statement.

(1) Factor out the greatest common factor. If the greatest common factor is 1, just retype the polynomial. $32k^{4}+22k^{3}-9k-33$ $\square $
