Final answer:
To complete the missing spaces in the box for the expression 3x²-11x²+12x-4/x-1, simplify the expression and factor out the common factors in the numerator and denominator.
Step-by-step explanation:
To complete the missing spaces in the box for the expression 3x²-11x²+12x-4/x-1, you need to simplify the expression by combining like terms and factor out the common factors in the numerator and denominator.
First, simplify the expression 3x²-11x²+12x-4 to get -8x²+12x-4.
Next, factor out the common factor of (x-1) from the numerator and denominator. The simplified expression is:
(-8x²+12x-4)/(x-1)
