You can put this solution on YOUR website! Find the roots of 13x=5x^2-6
5x^2-13x-6 = 0
5x^2-15x+2x-6 = 0
5x(x-3)+2(x-3)= 0
(x-3)(5x+2) = 0
x = 3 or x = -2/5

You can put this solution on YOUR website! 13x = 5x^2 -6
,
0=5x^2 -13x -6
,
( 5x +2)(x-3) =0
,
5x +2 =0,,,,,x=-2/5
,
x-3 = 0,,,,,x=3
,
checking
substitute into original eqn,,,both ok
