Answer:

B. 6 is also a factor of this trinomial.

Step-by-step explanation:

We have been given a trinomial 6x^2-18x+12. A student gives the answer (x-2)(x-1).

To figure out student's mistake, let us factor our given trinomial by splitting the middle term.  

6x^2-18x+12    

6x^2-12x-6x+12    

6x(x-2)-6(x-2)    

(6x-6)(x-2)    

6(x-1)(x-2)  

Therefore, 6 is also a factor of our given trinomial and option B is the correct choice.

Graph x^3 - 3x^2 + 2 = 0.1 - x What are the solutions of the equation?
liq [111]

Answer:

x=-0.6,x=1.52,x=2.08

Step-by-step explanation:

Let f(x)=x^3-3x^2+2.

and

g(x)=0.1-x

The graph of the two equations are shown in the attachment.

The points where the two graphs intersected are: (-0.6,0.7),(1.52,-1.42),(2.08,-1.98)

The x-coordinates of the intersection points are the solutions to x^3-3x^2+2=0.1-x.

Therefore the solutions are: x=-0.6,x=1.52,x=2.08
