Question 195656
{{{x=-4}}} or {{{x=8}}} Start with the given solutions.



{{{x+4=0}}} or {{{x-8=0}}} Move the values to the left side



{{{(x+4)(x-8)=0}}} Combine the equations using the zero product property



{{{x^2-8x+4x-32=0}}} FOIL



{{{x^2-4x-32=0}}} Combine like terms.



So the quadratic equation is {{{y=x^2-4x-32}}}
