Answer:B) B)D)Step-by-step explanation:1. [tex]7x^3y+14x^2y^3-7x^2y^2[/tex] The GCF of all the term of the above polynomial is [tex]7x^2y[/tex] , hence we take it outside and form a bracket[tex]7x^2y(x+2y^2-y)[/tex] The polynomial within the bracket can not be factorized further hence this is our final answer. Option (B) is the right answer 2. [tex]5x(x+3)+6(x+3)[/tex] The GCF of all the term of the above polynomial is [tex](x+3)[/tex] , hence we take it outside and form a bracket[tex](x+3)(5x+6)[/tex] The polynomial within the bracket can not be factorized further hence this is our final answer. Option (B) is the right answer 3. [tex]8x^5+2x^4+4x^2[/tex]The GCF of all the term of the above polynomial is [tex]2x^2[/tex] , hence we take it outside and form a bracket[tex]2x^2(4x^3+x^2+2)[/tex] The polynomial within the bracket can not be factorized further hence this is our final answer. Option (D) is the right answer
