Simplify 9-3m+2(m^2-3m)

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

Step 1

Simplify each term.

Apply the distributive property.

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

Multiply $- 3$ by $2$ .

$9 - 3 m + 2 m^{2} - 6 m$

$9 - 3 m + 2 m^{2} - 6 m$

Step 2

Simplify by adding terms.

Subtract $6 m$ from $- 3 m$ .

$9 + 2 m^{2} - 9 m$

Move $9$ .

$2 m^{2} - 9 m + 9$

$2 m^{2} - 9 m + 9$
