Adding which terms to 3x^2y would result in a monomial? Check all that apply
GrogVix [38]

Answer:

-12x^2y and 4x^2y

Step-by-step explanation:

Given

3x^2y

Required

What added term would make it a monomial

Options

3xy

-12x^2y

2x^2y^2

7xy^2

-10x^2

4x^2y

3x^3

The given expression, 3x^2y has 2 variables; x and y

x has a power of 2 and y has a power of 1.

This implies that, the next term to be added must have y to the power of 1 and x to the power of 2

From the list of given options, only 2 options satisfy this condition.

-12x^2y

4x^2y

When these two terms are added to 3x^2y, the result is a monomial.

i.e.

3x^2y - 12x^2y = -9x^2y

3x^2y + 4x^2y = 7x^2y
