Step 1

Move all the expressions to the left side of the equation.

Tap for more steps...

Step 1.1

Subtract $3 x^{2}$ from both sides of the equation.

$- 3 x^{2} = - 12 x - 15$

Step 1.2

Add $12 x$ to both sides of the equation.

$- 3 x^{2} + 12 x = - 15$

Step 1.3

Add $15$ to both sides of the equation.

$- 3 x^{2} + 12 x + 15 = 0$

Step 2

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

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

Step 3

The standard form is $- 3 x^{2} + 12 x + 15$ .

$- 3 x^{2} + 12 x + 15 = 0$
