Question

5x square -6x-2=0 Quadratic equation by fromula​

Answer 1

Step-by-step explanation:

a=5, b=-6, c=-2

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

$x = \frac{ - ( - 6) + - \sqrt{ {( - 6)}^{2} - 4(5)( - 2)} }{2 \times 5}$

$x = \frac{6 + - \sqrt{36 + 40} }{10}$

$x = \frac{6 + - \sqrt{76} }{10}$

$x = \frac{6 + - \sqrt{4 \times 19} }{10}$

x=(3±√19)/5
