Question

Place the indicated product in the proper location on the grid. (a+b-c)(a+b+c)

Answer 1

Answer:

The required location on the gird is shown below.

Step-by-step explanation:

Consider the provided expression.

We need to place the indicated product in the proper location on the grid.

First open the parenthesis as shown:

$(a+b-c)(a+b+c)=a(a+b+c)+b(a+b+c)-c(a+b+c)$

$(a+b-c)(a+b+c)=a^2+ab+ac+ab+b^2+bc-ac-bc-c^2$

Now add the like terms as shown:

$(a+b-c)(a+b+c)=a^2+b^2-c^2+2ab$

Hence, the required location on the gird is $(a+b-c)(a+b+c)=a^2+b^2-c^2+2ab$
