x=
x= -4
Step-by-step explanation:
Subtract 2x - 10 from both sides.
x= \frac{ -(26) +/ \sqrt{(676-4(6)(8)} }{2(6)}
x= \frac{ -(26) +/ \sqrt{(676-192} }{2(6)}
x= \frac{ -(26) +/ \sqrt{(484} }{2(6)}
x= \frac{ -26 +/ 22}{2(6)}
x= \frac{ -26 +/ 22}{12}
x= \frac{ -26 + 22}{12} = -0.33333333333333 = -1/3
x= \frac{ -26 - 22}{12} = -4
