Question

x*-7x+10=0 ussado o baskara

Answer 1

$x^{2} -7x+10$

$x = \frac{-b +/- \sqrt{ b^{2} -4 *a*c } }{2*a}$

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

$x = \frac{7+/- \sqrt{49 - 40} }{2}$

$x = \frac{7+/- \sqrt{9} }{2}$

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

$x' = \frac{7+3}{2} = \frac{10}{2} = 5$
$x'' = \frac{7-3}{2} = \frac{4}{2} = 2$

S={5,2}

Answer 2

a: 1 b:-7 c: 10
▲: -b* - 4ac
▲: -(-7)* - 4 ×1×10
▲: 49 - 40
▲: 9

Bhaskara

X= - b +/- raiz quadrada de ▲ sobre 2 x a
X= - (-7) +/- RQ ▲
2×1

X= 7 +/- 3
2

X' = 7+3. X' = 10 X' = 5
2 2

X" = 7-3. X" = 4 X" = 2
