- b ± √b² - 4ac
2a
c)x2 + 7x + 10 = 0​

Answer 1

$x2 \: + \: 7x \: + \: 10 \: = \: 0$

$2x \: + \: 7x \: + \: 10 \: = \: 0$

$9x \: + \: 10 \: = \: 0$

$9x \: = \: - 10$

$x \: = \: - \frac{10}{9}$

Answer 2

Respuesta:

x^2+7x+10 = 0

X = (-(7)+-√((7)^2-4(1)(10)))/(2×1)

X = ( -7+-√(49-40))/2

X = ( -7+-√(9))/2

X = ( -7+-3)/2

X1 = (-7-3)/2

X1 = -5

X2 = ( -7+3)/2

X2 = -2
