Question

Factor completely: −3x2 + 6x − 9

Answer 1

Factor out the -3
(-3)(x^2-2x+3)

Answer 2

Answer:

$-3(x^2-2x+3)$

Step-by-step explanation:

The given expression is

$-3x^2+6x-9$

The GCF of the expression is -3.

$-3(x^2-2x+3)$

Now, let us see if we can further factor the expression  $(x^2-2x+3)$ or not

the middle term is -2x

And we can't write the factor of 3 which gives -2 on addition/subtraction and 3 on multiplication

Hence, it is a prime expression.

Therefore, the factored form is

$-3(x^2-2x+3)$
