Answer: 1.  1*f*(x)-(-(x+4)^2-4)=0

STEP

1

:

Equation at the end of step 1

 fx - x2 - 8x - 12  = 0

STEP

2

:

Solving a Single Variable Equation:

2.1     Solve   fx-x2-8x-12  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    2*f*(x)-((x-1)^2)=0

STEP

1

:

1.1     Evaluate :  (x-1)2   =    x2-2x+1

Equation at the end of step

1

:

 2fx - x2 + 2x - 1  = 0

STEP

2

:

Solving a Single Variable Equation:

2.1     Solve   2fx-x2+2x-1  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.
