1. Remember, evaluate means to plug in the value for the specified

variable.

w

Evaluate: (x - 3) 2 + 2x - 4 for x = 5

Value: 10

Step-by-step explanation:

1. Let us first write down the expression, changing it a bit to our convenience: 2 (x - 3) + 2x - 4

2. Substitute this value of x into the expression as such:

2 (5 - 3) + 2 (5) - 4

3. Now we can approach this first part of the problem in two ways:

Option 1. distribute the 2 to the 5 and then the - 3, in 2 (5 - 3)

Option 2. subtract 3 from 5, then multiply 2 by that value

4. Given such, let us try the 2nd option for simplicity, and carry on with our calculations: 2 (2) + 2 (5) - 4

5. Now apply algebra and solve this expression:

2 (2) + 2 (5) - 4 = 4 + 10 - 4 = 14 - 4 = 10
