Find the value of this expression if x = 3. x2 + 3 x-1

1. 9

2. 2

Step-by-step explanation: First you would plug in the number for the variable then add or subtract. Instead of x2 + 3, it would be 3* 2 + 3 which is 9

If we replace both equations with the value for x, then it would look like this.

(3)2+3

3-1

Now, you solve. But remember to solve in this order.

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

The acronym is PEMDAS. Do note that multiplication and division are interchangeable. So if division comes before multiplication in an equation, you can do division first. It's the same for addition and subtraction also.

3 times 2 is 6. Plus 3 is 9

3 minus 1 is 2.

So your answer- (3)2+3=9
3-1=2
