Answer:

First, we need to simplify the expression by combining like terms. We have -4 + 3x^2-3 and -1. We can combine the like terms -4 and -1 to get -5.

Now, the expression can be rewritten as -5 + 3x^2-3. Next, we need to use the order of operations to evaluate the expression. The first step is to simplify any terms within parentheses, so we simplify 3x^2-3 to 3x^2-3 = 3x^2-3.

Now, the expression can be rewritten as -5 + 3x^2-3. The next step is to perform any multiplication or division, so we multiply 3 with x^2 to get 3x^2.

The expression is now -5 + 3x^2. The last step is to perform any addition or subtraction, so we add -5 and 3x^2 to get 3x^2-5.

Therefore, the answer to the expression is 3x^2-5.
