If you are trying to simplify this, which is the only thing I see doable, here are the steps.

First: factor out x^2-9x+14, which is (x-7)(x-2).

We then get [(x-7)(x-2)]/(x-7)

You can cancel out the x-7 on the numerator and denominator, which leaves us with x-2.

Multiply the exponent of x by 2giving

The answer is

x^2 evaluates to 

Multiply x and 9

Multiply x and 1

 

The x just gets copied along.

The answer is x

x

9*x evaluates to 9x

x^2-9*x evaluates to 

The answer is

x^2-9*x+14 evaluates to 

To divide by x

divide each term in by x term by term.

To divide by x

 

Divide by x by subtracting the exponents, and keeping the x, to get x

The answer is x

 ÷ x = x

To divide x by x

 

Divide x by x by subtracting the exponents, and keeping the x, to get 1

Why 1? since subtracting the exponents gives zero, the x completely drops out.This because anything (other than 0) to the 0th power is 1.

-9x ÷ x = -9

To divide 1 by x

 

The x just gets copied along in the denominator.

The answer is

14 ÷ x =

(x^2-9*x+14)/x evaluates to 

-9 - 7 = -16

The answer is

(x^2-9*x+14)/x-7 evaluates to
