I presume that you are asked of the quadratic equation with the given roots.
Given the roots as 1/4 and 4 you'll have it as:
since x = 1/4, x = 4 then
(x - 1/4)(x - 4) = 0
distributing you'll have:
x² -4x -1/4x +1 = 0
x² - 17/4x + 1 = 0
taking away the denominator, we multiply the whole equation with 4. then you'll have the quadratic equation as:
4x² - 17x + 4 = 0
