Factor 9x^4-18x^3+27x^2

$9 x^{4} - 18 x^{3} + 27 x^{2}$

Step 1

Factor $9 x^{2}$ out of $9 x^{4}$ .

$9 x^{2} (x^{2}) - 18 x^{3} + 27 x^{2}$

Step 2

Factor $9 x^{2}$ out of $- 18 x^{3}$ .

$9 x^{2} (x^{2}) + 9 x^{2} (- 2 x) + 27 x^{2}$

Step 3

Factor $9 x^{2}$ out of $27 x^{2}$ .

$9 x^{2} (x^{2}) + 9 x^{2} (- 2 x) + 9 x^{2} (3)$

Step 4

Factor $9 x^{2}$ out of $9 x^{2} (x^{2}) + 9 x^{2} (- 2 x)$ .

$9 x^{2} (x^{2} - 2 x) + 9 x^{2} (3)$

Step 5

Factor $9 x^{2}$ out of $9 x^{2} (x^{2} - 2 x) + 9 x^{2} (3)$ .

$9 x^{2} (x^{2} - 2 x + 3)$
