3x2+x+2

To simplify the expression 3x2 + x + 2, we follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction):

Step 1: Simplify any exponents or powers if there are any. In this expression, there are no exponents.

Step 2: Perform any multiplication or division from left to right. In this case, we have 3 multiplied by x2. Multiplying 3 by x2 gives us 3x2.

Step 3: Perform any addition or subtraction from left to right. In this case, we have 3x2 + x + 2. Since there is no like terms, we cannot combine them.

So the simplified form of 3x2 + x + 2 is just 3x2 + x + 2.
