Question

2x²-4x+5-1/3(x²-5x+7)​

Answer 1

Step-by-step explanation:

$2 {x}^{2} - 4x + 5 - \frac{1}{3}( {x}^{2} - 5x + 7) \\ 2 {x}^{2} - 4x + 5 - \frac{1}{3} {x}^{2} + \frac{5}{3}x - \frac{7}{3} \\ (2 {x}^{2} - \frac{1}{3} {x}^{2}) + ( - 4x + \frac{5}{3}x) + (5 - \frac{7}{3}) \\(\frac{6 {x}^{2} - {x}^{2}}{3}) + ( \frac{ - 12x + 5x}{3}) + ( \frac{15 - 7}{3} \\ ( \frac{5 {x}^{2} }{3}) + ( - \frac{7x}{3}) + ( \frac{8}{3}) \\ \frac{ {5x}^{2} }{3} - \frac{7x}{3} + \frac{8}{3} \\ \frac{5 {x}^{2} - 7x + 8 }{3}$
