Answer:
2nd choice [tex]x^2-x+4[/tex] is correct.
Step-by-step explanation:
We need to find about which polynomial is represented by the algebra tiles.
so we just need to collect all terms written on tiles then combine them.
Notice that - means -1 and + means +1
Row wise terms are:
[tex]+x^2+x^2-x^2[/tex]
[tex]-x-x+x[/tex]
[tex]-x+x[/tex]
[tex]-1+1+1+1[/tex]
[tex]-1+1+1+1[/tex]
Now combine like terms:
[tex]+x^2-x+4[/tex]
Hence 2nd choice is correct.
