Question

3(x+y)^2-(xy)2 x=3 y=-5

Answer 1

The value of the expression when x = 3 and y = -5 is -213

What are algebraic expressions?

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:

• x = 3
• y = -5

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
