$- 4 x - 7 x^{2} + 15 = - 5 x^{2}$

Step 1

Add $5 x^{2}$ to both sides of the equation.

$- 4 x - 7 x^{2} + 15 + 5 x^{2} = 0$

Step 2

Add $- 7 x^{2}$ and $5 x^{2}$ .

$- 4 x - 2 x^{2} + 15 = 0$

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

Reorder $- 4 x$ and $- 2 x^{2}$ .

$- 2 x^{2} - 4 x + 15 = 0$
