need help with THIS quadratic function!
actually i need help on this quadratic function
f(x) = -x2 + 10x
here is my work
f(x) = -x2 + 10x
f(x) = -x2 + 10x + 25 - 25 ((i divided 10 with 2 and then i squared it to get 25, then i added and subtracted 25 to keep the function even))
f(x) = -1(x - 5)2 - 25
here is where i am stuck... how can i factor -x2 + 10x + 25?
