Write the equation in standard form. $9 - 10 x = - x ^ { 2 }$
A) $x ^ { 2 } + 10 x + 9 = 0$
B) $9 + 10 x = - x ^ { 2 }$
C) $x ^ { 2 } - 10 x + 9 = 0$
D) $9 - x ^ { 2 } = 10 x$
E) $x ^ { 2 } + 10 x - 9 = 0$

Quizplus · Accepted Answer

To put the equation in standard form, we need to move all the terms to one side so that the constant term is on the right side of the equation. Adding $x ^ { 2 }$ to both sides, we get: 
$$x ^ { 2 } - 10 x + 9 = 0$$
So the correct answer is C.
