Hello :
<span> x4 − 9x2 − 4x + 12 = x²(x²-9)-4(x-3)
=x²(x-3)(x+3)-4(x-3)
= (x-3)(x²(x+3)-4)
= (x-3)(x3+3x²-4)
= (x-3)(x-1)(x²+4x+4)
</span>x4 − 9x2 − 4x + 12 = (x-3)(x-1) (x+2)²
<span> potential roots is : 3 ; 1 :-2</span>
C. the number goes up by one tenth. changing the 0 in the tenth place to a one.
