Does anyone knows this and can show me the work, please?

hartnn · Answer

Compare your quadratic equation with 
$ax^2+bx+c=0$
find a,b,c
then calculate $b^2-4ac$
if it is perfect square then it can be factored, else it is prime

anonymous · Answer

Oh, but what does this equation equal too?

hartnn · Answer

sorry here its quadratic function f(x)= $ax^2+bx+c$
which equation ?
