Find the sum
6x²y,-8x²y,-4x²y,3x²y

sara369: u can mark as best

kunalraju45: mak my ans s best

william: (6x^2 y+ 3 x^2y) - ( 8x^2y + 4 x^2y) = 9 x^2y - 12x^2y = -3x^2y

sara369: exactly this ans is correct

kvnmurty: Harshita, it looks good if u use equation editor and symbols - to type in question. u can do that by clicking on Pi button and Omega button while creating question. thanks.

Since all the terms in x and y have same power to x and y respectively, we add the coefficients. Thus,

$6 x^{2} y + (-8 x^{2} y) + (-4 x^{2} y)+(3 x^{2} y)\\ \\ = (6 - 8 - 4 + 3) x^{2} y = -3 x^{2} y \\$
