Question

Compute the following:
[a²+b² b²+c²]. + [ 2ab 2bc ]

[a²+ c² a² +b²] + [-2ac 2ab]​

Answer 1

Answer:

• [$(a+b)^{2}$             $(b+c)^{2}$]

        [$(a-c)^{2}$            $(a+b)^{2}$ ]2x2

Step-by-step explanation: this is a 2x2 matrix eqn

• [a2+b2   b2+c2]        +    [ 2ab     2bc ]

        [a2+c2    a2+b2]2x2  +  [-2ac      2ab]2x2

• [ a2+b2+2ab          b2+c2+2bc]

        [a2+c2-2ac             a2+b2+2ab]

• [$(a+b)^{2}$             $(b+c)^{2}$]

        [$(a-c)^{2}$            $(a+b)^{2}$ ]2x2
