+964 Fill in the blanks to make a quadratic whose roots are 5 and -5.
x^2 + ___ x + ___
+120 I think that we should start with factoring/finding a quadratic formula that we know has a root of 5 or -5
we can get a factored version of a quadratic formula with roots of 5 and -5 ==> (x-5)(x+5) = we can get x^2-25 if we simplefy it
so your anwser would be
x^2 - 0x + (-25)
thanks
