Question

×2-5×+6 me ajudem nessa dai ​

Answer 1

a resposta e igual a -3x +6

Answer 2

${x}^{2} - 5x + 6 = 0 \\ a = 1 \\ b = - 5 \\ c = 6 \\ \\ d = {b}^{2} - 4ac\\ d = {( - 5)}^{2} - 4 \times 1 \times 6\\ d = 25 - 24\\ d = 1 \\ \\ x1 = \frac{ - b + \sqrt{d} }{2 \times a} \\ x1 = \frac{ - ( - 5) + \sqrt{1} }{2 \times 1} = \frac{5 + 1}{2} = \frac{6}{2} = 3 \\ \\ x2 = \frac{ - b - \sqrt{1} }{2 \times a} \\ x2 = \frac{ - ( - 5) - \sqrt{1} }{2 \times 1} = \frac{5 - 1}{2} = \frac{4}{2} = 2$

Espero ter ajudado!! ^_^
