Combine the like terms to simplify the expression: 4 + 7xy^2 + 5y^3 + 10x –4xy^2 – 8x – 4y^3 + 9 A. y^3 + 3xy^2 + 2x + 13 B. y^3 – 3xy^2 + 2x + 9 C. y^6 + 3x^2y^2 + 10x + 13 D. y^3 + 3xy^2 + 10x + 13

    It looks intimidating but it's really easy. Just add up the like terms. e.g. 7xy^2 is a like term with -4xy^2

    No, add 5y^3 to -4y^3 then add 7xy^2 to -4xy^2 then add 10x to -8x and then add 9 to 4

    You aren't adding the exponents, so for example x^2 + 4x^2 would just be 5x^2

    You shouldn't have to guess. 57^3 -4y^3 is y^3 7xy^2 -4xy^2 is 3xy^2 10x-8x is 2x and 4+9 is 13
