Answer:
If [tex](-x^2 + y^2)[/tex] is subtracted from [tex](x^2 + y^2)[/tex], the difference is: [tex]\mathbf{2x^2}[/tex]
Option A is correct option.
Step-by-step explanation:
If [tex](-x^2 + y^2)[/tex] is subtracted from [tex](x^2 + y^2)[/tex], we need to find the difference.
When finding the difference the term after from comes first.
We can write:
[tex](x^2 + y^2)-(-x^2 + y^2)[/tex]
Now finding difference:
Multiply minus sign with terms inside the bracket
[tex]=x^2 + y^2+x^2 - y^2[/tex]
Now combine the like terms
[tex]x^2 +x^2+ y^2 - y^2\\=2x^2+0\\=2x^2[/tex]
So, If [tex](-x^2 + y^2)[/tex] is subtracted from [tex](x^2 + y^2)[/tex], the difference is: [tex]\mathbf{2x^2}[/tex]
Option A is correct option.
