Answer:
1. Replace each variable in the expression with the assigned value.
2. Perform the operations in the expression using the correct order of operations.
Step-by-step explanation:
Here's an example. Let's evaluate the expression 2x³ – x² + y
for x = 3 and y = –2.
Replace each variable in the expression with its value. In this example, this means each x becomes a 3 and each y becomes a -2. (It's a good idea to use parentheses to keep track of this.)
So 2(3)³ - (3)² + (-2)
Perform operations with exponents.
2(27) - 9 + (-2)
Perform operations with multiplication and division.
54 - 9 +(-2)
Perform operations with addition and subtraction
