Answer 4

These algebra problems hinge on the Distributive Property of Multiplication. Perhaps you've heard of the "FOIL" method (first, outer, inner, last).
Example: (a+b)(c+d)=ac+ad+bc+bd. Have you? Have you any examples to refer to in your class materials?

Answer 5

No:( @mathmale

Answer 6

Happy to help...but I do expect that you do some basic reading and look for examples of algebraic multiplication (including the FOIL method) beforehand. Willing to do that?

Answer 7

Please see the following, online:

Answer 8

Example 2: (x+2y)(x-y)=x^2+2xy-xy-2y^2), using the same FOIL method.
The First terms are x and x; their product is x^2.
The Outer terms are x and -y; their product is -xy.
The Inner terms are 2y and x; their product is 2xy.
The Last terms are 2y and -y; their product is -2y^2.
Just combine these four products to obtain the final answer.

Apply this procedure to the problems you've posted.

I apologize, but will have to log off the 'Net now. Good luck!
