x = - 1/4

Answer 2

Respuesta:

Answer

$\sf \: 12x {}^{2} \: - \: 5x \: - \: 2 = 0$

Use the quadratic formula

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

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

$\sf \: 12x {}^{2} - x5 - 2 = 0 \\ a = 12 \\ b = - 5 \\ c = - 2 \\ \sf \: x = \frac{ - ( - 5) + \sqrt{( - 5) {}^{2 } - 4.12( - 2 } }{2. \: 12}$
