Answer: 1 Mark

According to question:

$=\left[\right(2x^2+3y)+(5x^2+3x\left)\right]-(8y^2+3x^2+2x+3y)$

$=[2x^2+3y+5x^2+3x]-(8y^2+3x^2+2x+3y)$

$=[7x^2+3y+3x]-(8y^2+3x^2+2x+3y)$

$=[7x^2+3y+3x-8y^2-3x^2-2x-3y$

$=4x^2+x-8y^2$

Hence, the expression represented by the above symbols is $4x^2+x-8y^2$.
