For quadratic equation:
a x² + b x + c = a ( x  x1 ) ( x  x2 )
where x1 and x2 are roots
In this case x1 =  3 , y = 1 / 4
a x² + b x + c = a [ x  (  3 ) ] ( x  1 / 4 ) =
a ( x + 3 ) ( x  1 / 4 ) = a ( x² + 3 x  1 / 4 x  3 / 4 ) =
a ( x² + 12 / 4 x  1 / 4 x  3 / 4 ) = a ( x² + 11 / 4 x  3 / 4 )
where a is some real number ( leading coefficient of quadratic equation ) 👍

since you don't specify any particular form, just use the roots directly
(x+3)(4x1) = 0
You can massage that as you will. 👍
