Answer 2

Step-by-step explanation:

${6x}^{2} + 7x - 10 = 0$

$Here, a = 6, b = 7, c = - 10.$

$∴ \: \: \: \: \: \: \: \: \: \: \: From \: x \: = \frac{ - b± \sqrt{b²-4ac} }{2a} ,$

$x = \frac{ - 7± \sqrt{ {7}^{2} - 4.6( - 10)} }{2.6} \\ \\ \: \: \: \: \: \: \: \: = \frac{ - 7± \sqrt{49 + 240} }{12}$

$\: \: \: \: \: \: \: \: \: \: = \frac{ - 7± \sqrt{289} }{12} = \frac{ - 7±17}{12}$

On taking ( +) sign,

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{ - 7 + 17}{12} = \frac{ 10 }{12} = \frac{5}{6}$

On taking ( -) sign,

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{ - 7 - 17}{12} = \frac{ - 24}{12} = - 2$

$∴ \: \: \: \: \: \: \: \: \: \: \: \: \: \: x = \frac{5}{6} , - 2.$
