is a factor because (x+2)(x^3+x^2+2x-4)=x^4+3x^3+4x^2-8
Answer is (x-1)and (x-2).First make the equation 3x^2- 9x+6=0. then divide both sides by 3 and then the two factors are (x-1)(x-2)
Undefined slope.....means it is a vertical line. A vertical line is represented by x = a number...with that number being the x coordinate of ur point (2,-8).
so the equation would be : x = 2......this cannot be written in slope intercept form because of the undefined slope
