I tried just about every online calculator they had but they said its not factorable
HI Rayanna;
X^{2}-16X+5
It is not factorable. As far as I know, there is only way to resolve this.
First, let's do FOIL. I do not know if you are familiar with this.
FIRST
INNER
OUTER
LAST
(x- )(x+ )
or
(x+ )(x+ )
or
(x- )(x- )
FIRST...x^{2}
INNER & OUTER will be
?x-?x=-16x
LAST...
? times ?=+5
Obviously
+1 times +5 =5
or
-1 times -5 =5
There is no other option.
So...
(x-5)(x-1)
x^{2}-5x-1x+5
x^{2}-6x+5
I believe there was a typographical error in the equation. Please re-check it. If there is not, then this must be the factoring result...
((x-5)(x-1))-10x
I hope this helps. Please let me know if you need anything else.
