Question

How many terms are in the simplified expression -3x 2 + 2y 2 + 5xy - 2y + 5x 2 - 3y 2

Answer 1

there are 6 terms in the simplified expression

Answer 2

-3x 2 + 2y 2 + 5xy - 2y + 5x 2 - 3y 2 should be written with " ^ " to indicate exponentiation:

-3x^2 + 2y^2 + 5xy - 2y + 5x^2 - 3y^2

Next step is to combine like terms (simplify):

5x^2 - 3x^2 + 2y^2 - 3y^2 + 5xy - 2y  becomes  
      2x^2       -         y^2      + 5xy - 2y.

This has FOUR terms.
