Question

I was in the middle of a session and my phone died. I need help solving this algebraically and numerically (there’s two photos for the question btw)

Answer 1

From the table

Squaring one factor of column A and adding it to one fator from column B

First row,

`(x-y)^2_{_{_{_{_{}}}}}+_{}(x^2+2xy+y^2)`

Solving the above,

`\begin{gathered} =(x^2-xy-xy+y^2)+(x^2+2xy+y^2) \\ =(x^2-2xy+y^2_{})+(x^2+2xy+y^2) \\ =x^2+x^2-2xy+2xy+y^2+y^2 \\ =2x^2+2y^2=2(x^2+y^2) \\ =2(x^2+y^2) \end{gathered}`

Second row,

`=(x+y)^2+(x^2-2xy+y^2)`

Solving the above,
