To simplify the expression \( 18x^2 - 12x + 63x \), we first combine like terms.
- Combine the \( -12x \) and \( +63x \): \[ -12x + 63x = 51x \]
Now the expression becomes: \[ 18x^2 + 51x \]
- Next, we can factor out the common factor from the entire expression: \[ 3x(6x + 17) \]
So, the simplified form of \( 18x^2 - 12x + 63x \) is: \[ 3x(6x + 17) \]
However, based on the choices provided:
- \( 6x - 4 + \frac{2}{x} \)
- \( 6x - 2 \)
- \( 6x^2 - 4x + 2 \)
- \( 6x^3 - 4x^2 + 2x \)
None of the options match our simplified expression \( 3x(6x + 17) \).
Thus, please check the options provided, as none of them are correct for the expression \( 18x^2 - 12x + 63x \).
