Rewrite the function f(x ) = x2−16x+63 in factored form. hint: factored form is (x-r1)(x-r2)

Hello! first you find what numbers multiply to 631 and 633 and 217 and 9you look and see what numbers add to 16only 7 and 9 add to 16the answer is (x - 7)(x - 9)hope this !

Don't you mean  f(x ) = x^2−16x+63?   " ^ " denotes exponentiation.note that one possible set of factors of 63 is {7,9}, and that 7+9 = 16.thus,    f(x ) = x^2−16x+63 = (x-7)(x-9).  note that the middle terms are -7x and -9x, and that these sum up to -16x, as they must.

How many groups are there?
