Which expression shows the sum of the polynomials with like terms grouped together? 10x^2y+2xy^2-4x^2y

first find the similar term, the similar term is x^2y.

10x^2y + 2xy^2 - 4x^2y

group together the similar term and place them in a parenthesis

then perform the operation to simplify the expression.

= (10x^2y - 4x^2y) + 2xy^2

= (6x^2y) + 2xy^2

= 6x^2y + 2xy^2 is the sum of the polynomial
