How do you combine like terms in $3\frac { 1} { 2} x y ^ { 2} - 2\frac { 4} { 5} x ^ { 2} y - 2\frac { 1} { 2} y ^ { 2} x + 2\frac { 4} { 5} x ^ { 2} y$ ?

$xy^2$

$3(1/2)xy^2)color(red)ul (-2(4/5)x^2y)-2(1/2)y^2x color(red) ul(+2(4/5)x^2y)$
$=3(1/2)xy^2-2(1/2)y^2x$
$((7xy^2)-(5y^2x))/2=(2xy^2)/2=xy^2$
