What is the standard form of the equation [tex]-27 = -10x - 7x^2[/tex]?

A. [tex]-7x^2 - 10x - 27 = 0[/tex]
B. [tex]7x^2 = 27 - 10x[/tex]
C. [tex]7x^2 + 10x - 27 = 0[/tex]
D. [tex]-7x^2 + 10x - 27 = 0[/tex]

Answer :

Let's find the standard form of the equation [tex]\( -27 = -10x - 7x^2 \)[/tex].

The standard form of a quadratic equation is usually written as [tex]\( ax^2 + bx + c = 0 \)[/tex].

To convert the given equation into standard form, we need to set one side of the equation to zero.

1. Start with the given equation:
[tex]\[
-27 = -10x - 7x^2
\][/tex]

2. To get zero on one side, add 27 to both sides of the equation:
[tex]\[
0 = -10x - 7x^2 + 27
\][/tex]

3. Rearrange the terms to match the standard form [tex]\( ax^2 + bx + c = 0 \)[/tex]:
[tex]\[
-7x^2 - 10x - 27 = 0
\][/tex]

Now, we have the equation in standard form:
[tex]\[
-7x^2 - 10x - 27 = 0
\][/tex]

Therefore, the standard form of the given equation is [tex]\( -7x^2 - 10x - 27 = 0 \)[/tex].
