How do you factor 9-6x+x^2

Step-by-step explanation:

rewrite 9-6x+ as -6x+9.  (this step isn't necessary, but it's easier when the bigger term is in front)

There's two ways: using the quadratic formula, or just doing it in your head (for simple ones)

For the simple way:

think about what numbers not only multiply to equal c (represented by 9 in this case) but also add to equal -6 (represents b in this problem).  There are two numbers for this problem that work: -3 and -3.  So you would write the factored form as (x-3)(x-3)

Quadratic formula:

The formula is ±

This formula works for equations in the form of a+bx+c.

Substitute in the values to get:

simplify:

3±

3±

the answer is 3, which is the x-intercept.  Write that as (x-3)(x-3)

it could be 1,3 and more others to create a cylinder.
