If 5 and 7 are the roots of the equation `|{:(x,4,5),(7,x,7),(5,8,x):}|=0`, then what is the third root ?

The root of the equation |(x,3,7),(2,x,-2),(7,8,x)|=0 are -

If 5 is one root of the equation |{:(x,3,7),(2,x,-2),(7,8,x):}|=0 then find the other two roots of the equation.

If 5 is one root of the equation |(x,3,7),(2,x,-2),(7,8,x)|=0 then the other two roots of the equation are:

The roots of the equation 5x^(2)+10x-7=0 are

The roots of the equation 5x^(2)+10x-7=0 are

The roots of the equation |[0,x,16],[x,5,7],[0,9,x]|= 0 are
