Add :4x2 y, – 3xy2 , –5xy2 , 5x2 yAdd :4x2 y, – 3xy2 , –5xy2 , 5x2 y

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
