write a quadratic equation in the variable x having given the numbers as sollutions type the equation in standard form ax^2+bx+c=0. solution 4 only solution
If 4 is the only solution to a "quadratic", then 4 must appear as a double-root.
so the factored form must be
(x-4)(x-4) = 0
expand it and you have your equation.
