Dear StudentWhen term have the same algebraic factors, they are like terms.Then, we have to add the like terms= 4x2y + (-3xy2) + (-5xy2) + 5x2y= 4x2y + 5x2y–3xy2–5xy2= x2y (4 + 5) + xy2 (-3 - 5)= x2y (9) + xy2 (- 8)= 9x2y–8xyThanks

Dear Student

When term have the same algebraic factors, they are like terms.
Then, we have to add the like terms
= 4x²y + (-3xy²) + (-5xy²) + 5x²y
= 4x²y + 5x²y–3xy²–5xy²
= x²y (4 + 5) + xy² (-3 - 5)
= x²y (9) + xy² (- 8)
= 9x²y–8xy

Thanks
