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

The explanation Marc can give

Jose is, you should have added 12 and –12 for the xy terms

Step-by-step explanation:

Josh calculation

-8x^2y-17xy^2+12xy-8+5x^2y-xy^2-12xy=-3x^2y-18xy^2+24xy-8

Correct calculation

-8x^2y-17xy^2+12xy-8+5x^2y-xy^2-12xy

Collect like terms

= -8x^2y+5x^2y-17xy^2-xy^2+12xy-12xy-8

= -3x^2y-18xy^2-8

The explanation Marc can give

Jose is, you should have added 12 and –12 for the xy terms.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
