The value of the expression when x = 3 and y = -5 is -213
<h3>What are algebraic expressions?</h3>
Algebraic expressions are expressions made up of variables and constants with mathematical operations such as addition, subtraction, division, multiplication, etc
From the expression given;
3(x+y)^2-(xy)2
Where:
Substitute the values into the expression
3 ( 3 + -5)^2 - ( 3 × -5 )^2
3 ( -2)^2 - ( -15)^2
3(4) - ( 225)
-12
Thus, the value of the expression when x = 3 and y = -5 is -213
