#### Question 6: Multiply: #### Answer 6: To multiply, we will use distributive law as follows:   Thus, the answer is #### Answer 7: To multiply, we will use distributive law as follows:

(x6y6)(x2+y2)=x6(x2+y2)y6(x2+y2)=(x8+x6y2)(y6x2+y8)=x8+x6y2y6x2y8 Thus, the answer is x8+x6y2y6x2y8x8+x6y2-y6x2-y8.

#### Answer 8: To multiply, we will use distributive law as follows:

(x2+y2)(3a+2b)=x2(3a+2b)+y2(3a+2b)=3ax2+2bx2+3ay2+2by2 Thus, the answer is 3ax2+2bx2+3ay2+2by23ax2+2bx2+3ay2+2by2.
