Question

Jose combined the like terms in the expression. Marc claims that he made a mistake.

Negative 8 x squared y minus 17 x y squared + 12 x y minus 8 + 5 x squared y minus x y squared minus 12 x y = negative 3 x squared y minus 18 x y squared + 24 x y minus 8


Jose asks Marc to explain how to fix his error. Which is the best explanation that Marc can give Jose?
Jose, you should have added 12 and –12 for the xy terms.
Jose, you should have added –8 and –5 for the for the x squared y terms.
Jose, you should have added –17 and 1 for the x squared y terms.
Jose, you should have added –8 and the two 12s for the xy terms.

Answer 1

So this would be equal to: -8^2 (y-17) (xy^2) + 12xy-8+5x^2 (y-xy)^2- 12xy?

Answer 2

The original equation at least.

Answer 3

I'm not sure what you mean.

Answer 4

If you convert (ignore my pun 😂) the words into numbers is that what it'd look like?

Answer 5

yes, it is an equation, just when I copied and pasted it, it *converted*

Answer 6

Wait no now that I read it again I realize that it is -8x^2y+5x^2y-17xy^2-xy^2+12xy-12xy-8
And once I use what Jose said it is: -3x^2y-18xy^2-8

So I believe because of this it would be A "Jose, you should have added 12 and –12 for the xy terms." because after looking at it you see that the xy variables are 12xy and -12xy which cancel out which means there shouldn't be any xy in the equation only xy squared because of the -17xy^2

Answer: A. Jose, you should have added 12 and –12 for the xy terms

Answer 7

Thank you.
