Answer:
7xy+2x^2t
Explanation:
Simplify expression by collecting like terms.
So in:
5xy - x^2t + 2xy + 3x^2t, the like terms are 5xy and 2xy and -x^2t and 3x^2t
Complete the performance required for each pair:
5xy + 2xy = 7xy
- x^2t + 3x^2t = 2x^2t
Now, put them back together. Use a + sign between them because both are positive.
7xy+2x^2t
Hope this Helps
Good Luck.
