Step 2.1.1.1

Raise $3$ to the power of $2$ .

$- 1 \cdot 9 + 4 \cdot - 3 + 9 = 0$

Step 2.1.1.2

Multiply $- 1$ by $9$ .

$- 9 + 4 \cdot - 3 + 9 = 0$

Step 2.1.1.3

Multiply $4$ by $- 3$ .

$- 9 - 12 + 9 = 0$

$- 9 - 12 + 9 = 0$

Step 2.1.2

Simplify by adding and subtracting.

Step 2.1.2.1

Subtract $12$ from $- 9$ .

$- 21 + 9 = 0$

Step 2.1.2.2

Add $- 21$ and $9$ .

$- 12 = 0$

$- 12 = 0$

$- 12 = 0$

Step 2.2

Since $- 12 \neq 0$ , there are no solutions.
