Question

sendo a= 1, b= -7 e c = 10 os valores de x sao:

Answer 1

Resposta:

$x = \frac{ - ( - 7) \frac{ + }{ - } \sqrt{ {( - 7)}^{2} - 4 \times 1 \times 10 } }{2 \times 1}$

$x = \frac{7 \frac{ + }{ - } 3}{2}$

$x1 = \frac{7 + 3}{2} = \frac{10}{2} = 5$

$x2 = \frac{7 - 3}{2} = \frac{4}{2} = 2$

c) 2 e 5
