Answer:
A
Step-by-step explanation:
Consider the expression
[tex]6x^2y-3+x^2y+2xy^2+2xy-6[/tex]
which both girls are given.
In this expression there are like terms:
- [tex]6x^2y[/tex] and [tex]x^2y;[/tex]
- [tex]-3[/tex] and [tex]-6.[/tex]
Combine the like terms:
[tex]6x^2y+x^2y=7x^2y;[/tex]
[tex]-3+(-6)=-9[/tex]
So,
[tex]6x^2y-3+x^2y+2xy^2+2xy-6=7x^2y +2xy^2+2xy-9[/tex]
Correct option is A, Salina combined the [tex]x^2y[/tex] terms correctly, but then left [tex]+x^2y[/tex] term in her answer.
