I'm glad to hear that! However, please keep in mind that the answers may have changed or may be different for different versions of the test. It's important to double check with your teacher or study the material thoroughly to ensure the best results.
To simplify a polynomial, you need to combine like terms and arrange the terms in order of decreasing exponents.
Let's analyze each option provided:
A. -2x^2 + 2x + 3
B. 2x^2 - 2x - 3
C. 3x^2 - 2x - 3
D. 2x^2 - 2x + 3
In option A, there are no other terms with the same exponent as -2x^2, so it cannot be simplified.
In option B, there are no other terms with the same exponent as 2x^2, so it cannot be simplified.
In option C, there are no other terms with the same exponent as 3x^2, so it cannot be simplified.
In option D, there are no other terms with the same exponent as 2x^2, so it cannot be simplified.
Therefore, none of the given options can be further simplified.
