Isabella says that:

 $4x^2+x=5x^2$ 

Is Isabella correct? 

• Yes, the x has a secret 1 in front so 4 + 1 is 5 total

• No! x and x squared are NOT like terms

• Maybe yes? Maybe no?

Siham says that the expression

 $14y-2y^2$  
can NOT be simplified further. Is Siham correct or incorrect?

• She is correct, y and y squared are not like terms so you cannot simplify any further

• She is incorrect, 14 minus 2 is 12

• Maybe yes? Maybe no?
