Answer 1

Answer:

show that (x+1) is a factor at x^3+3x^2+3x+1

Answer 2

A = {3, 6, 9, 12, 15, 18, 21}

B = {4, 8, 12, 16, 20} C = = {2, 4, 6, 8, 10, 12, 14, 16}

D = {5, 10, 15, 20}

(i) A B = {3, 6, 9, 15, 18, 21}

(ii) AC {3, 9, 15, 18, 21} (iii) A D = {3, 6, 9, 12, 18, 21}

(iv) B A = {4, 8, 16,20}

(v) CA = {2, 4, 8, 10, 14, 16}

(vi) D-A = {5, 10, 20}

(vii) B C = {20}

(viii) B D = {4, 8, 12, 16} (ix) C B = {2, 6, 10, 14}

(x) D B = {5, 10, 15}

(xi) CD= {2, 4, 6, 8, 12, 14, 16} (xii) DC = {5, 15, 20}
