    Answer:

    x=\frac{19}{12}\\ or\\x=\frac{5}{12}

    Step-by-step 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{+}{}\frac{7}{12}

    ——————————

    x=1+\frac{7}{12}

    x=1-\frac{7}{12}

    ——————————

    1+\frac{7}{12}=\frac{(1*12)+(7*1)}{12}  =\frac{12+7}{12} =\frac{19}{12}

    ——————————

    1-\frac{7}{12}=\frac{(1*12)-(7*1)}{12}  =\frac{12-7}{12} =\frac{5}{12}
