Question

Simplify the second part​

Answer 1

Step-by-step explanation:

$( {x}^{2} - x) - \frac{1}{2} (x - 3 + 3 {x}^{2}) \\ \\ \\ ( {x}^{2} - x) - \frac{1}{2} (3 {x}^{2} + x - 3) \\ \\ \\ ( {x}^{2} - x) - \frac{(3 {x}^{2} + x - 3) }{2} \\ \\ \\ \frac{{2x}^{2} - 2x - 3 {x}^{2} - x + 3}{2} \\ \\ \\ \frac{ - {x}^{2} - 3x + 3 }{2}$
