Step-by-step explanation:

3 {x}^{2}  - 32x + 12 = 0 \\  ∴x =  \frac{ - 32∓(- 32^{2} - 4 \times 3 \times 12)    }{2 \times 3}  \\ \:  \:  \:  \:  \:  \:  \:  \:   =  \frac{ -32 ∓(1024 - 144)}{6}  \\   \:  \:  \:  \:  \:  \:  \:  \: =  \frac{ - 32∓880}{6}  \\   \\ if \: we \: take\: plus\:  then, \:x1 =  \frac{ - 32  + 880}{6}   \\ \:  \:  \:  \:  \:    \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  or,  \: x 1=  \frac{848}{6}  \\ \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \:  \:  \:  \:  \:  \: \:  \:  \: ∴x 1= 141.33 \\  \\ if \: we \: take \: minus \: then, \: x2 =  \frac{ - 32 - 880}{6}  \\ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   or,x 2=  \frac{ - 912}{6}  \\ \:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\: \:  \:  \:  \:  \:  \: ∴x2 = 125

\bf\green {Hence,\: the \:value \:of \:x\: is\: 141.33\: and \:125. }
