${\tt{\purple{\underline{\underline{\huge{Answer:}}}}}}$

$\implies\sf {12x}^{2} + 8x - 20 = 0$

$\implies\sf {12x}^{2} + 20x - 12x - 20 = 0$

$\implies\sf4x(3x + 5) - 4(3x + 5) = 0$

$\implies\sf(4x - 4) = 0 \: \: or \: \: (3x + 5) = 0$

$\implies\sf4x = 4 \: \: or \: \: 3x = - 5$

$\implies \sf \: x = \cancel \dfrac{4}{4} \: \: or \: \: x = - \dfrac{5}{3}$

$\implies\sf \: x = 1 \: \: or \: \: x = - \dfrac{5}{3}$
