the answer is (x-3)(x-3)
( )( )
here's an easy way....
there are 2 bracket,since there are x to the power of 2,then fill each bracket with an x
(x )(x )
then look at the number without any unknown.
square root of that number is........
fill each bracket with square root of nine,that is 3
(x 3)(x 3)
then,look at the signs in the equation,its X^2-6x+9.
so,its (-)(+) right?
when negative meets positive,it will be negative.
so,put negative sign between x and three
and the answer is(x-3)(x-3).
try this method on another question.

Find two numbers that multiply to 9 and add to -6, then put them into this form (x+a)(x+b).
They are -3 and -3 in this case.
So the factored form is (x-3)(x-3).

that is a perfect square trinomial..
so the factor is the sq root of the polynomial
1st term:get the sq root of the 1st term
sq root x^2=x
2nd term:get the sq root of the 3rd term
sq root 9=3
answer:
(x-3)^2 [copy the sign of the 2nd term] [square the binomial]
