Answer:


x=(19)/(12)\\ or\\x=(5)/(12)

Explanation:


6x^2-x-2=0

a=6

b=-1

c=-2


x=-b\frac{+}{}\frac{\sqrt[]{b^2-4ac} }{2a}


x=-(-1)\frac{+}{}\frac{\sqrt[]{(-1)^2-4(6)(-2)} }{2(6)}


x=1\frac{+}{}\frac{\sqrt[]{1+48} }{12}


x=1\frac{+}{}\frac{\sqrt[]{49} }{12}


x=1\frac{+}{}(7)/(12)

------------------------------


x=1+(7)/(12)


x=1-(7)/(12)

------------------------------


1+(7)/(12)=((1*12)+(7*1))/(12) =(12+7)/(12) =(19)/(12)

------------------------------


1-(7)/(12)=((1*12)-(7*1))/(12) =(12-7)/(12) =(5)/(12)
