Step 2.1.2.1

Move $x$ .

$3 (x \cdot x) + 3 x \cdot - 2 + 7 x - 1 = 0$

Step 2.1.2.2

Multiply $x$ by $x$ .

$3 x^{2} + 3 x \cdot - 2 + 7 x - 1 = 0$

Step 2.1.3

Multiply $- 2$ by $3$ .

$3 x^{2} - 6 x + 7 x - 1 = 0$

Step 2.2

Add $- 6 x$ and $7 x$ .

$3 x^{2} + x - 1 = 0$

Step 3

To write a polynomial in standard form, simplify and then arrange the terms in descending order.

$a x^{2} + b x + c = 0$

Step 4

The standard form is $3 x^{2} + x - 1$ .

$3 x^{2} + x - 1 = 0$
