The value of the expression when z = -3 and y = -3 is 18

What are algebraic expressions?

An algebraic expression can be defined as an expression which is made up of variables and constants, along with algebraic operations such as addition, subtraction, division, multiplication and some others.

From the information given, we have;

  • zy + y²
  • y = -3
  • x = -3

Now, let's substitute the value of y as -3 and that of z as -3

We have;

= zy + y²

= -3( -3) + ( -3)²\

Expand the bracket

= 9 + 9

Add the values

= 18

Thus, the value of the expression when z = -3 and y = -3 is 18
