What is the completely factored form of f(x)=x3 4x2 7x 6?.

Y = -0.5 x -1  > eq 1
y = 0.25 x -4 > eq 2
by subtracting eq 1 from eq 2

0 = 0.25 x - 4 - (- 0.5 x -1)
   = 0.25 x - 4 + 0.5 x +1 
   = 0.75 x - 3 
by adding 3 to both sides
0 + 3 = 0.75x -3 +3 
3 = 0.75 x (by dividing both sides by 0.75)
x = 3 /0.75 =4 (substitute in eq 1)
y = -3

(4,-3)
