Question

x^2+6x-2=0
please tell .e​

Answer 1

Answer:

x² + 6x - 2 = 0

Use quadratic formula

$x = \frac{ - b ± \sqrt{ {b}^{2} - 4ac } }{2a}$

$x = \frac{ - 6 ± \sqrt{36 - 4 \times 1 \times ( - 2)} }{2 \times 1}$

$x = \frac{ - 6 ± \sqrt{36 + 8} }{2}$

$x = \frac{ - 6 ± \sqrt{44} }{2}$

$x = \frac{ - 6 ± 2 \sqrt{11} }{2}$

$x = - 3 + \sqrt{11} , \: \: x = - 3 - \sqrt{11}$

Hope you got your answer

Take care

Answer 2

$x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a}$

$x = \frac{ - ( - 6)± \sqrt{( {6)}^{2} - 4 \times - 2 \times 1} }{2 \times 1}$

$x = \frac{6 + \sqrt{6 - 8} }{2}$

$x = 3 + \sqrt{ - 2}$
