Introduction

In this article, we will explore the process of rewriting a cubic equation in a non-standard form. We will start with the given function $f(x) = x^3 + 3x^2 + 4x - 12$ and show that the equation $f(x) = 0$ can be rewritten in the form $x = \sqrt{\left(\frac{a(b-x)}{3+x}\right)}$ where $x \neq -3$. We will also find the constants $a$ and $b$.

Step 1: Factor the Cubic Equation

To rewrite the cubic equation in a non-standard form, we first need to factor the equation. We can start by factoring out the greatest common factor (GCF) of the terms.

f(x) = x^3 + 3x^2 + 4x - 12

We can see that the GCF of the terms is 1, so we cannot factor out any common factors. However, we can try to factor the equation by grouping the terms.

f(x) = (x^3 + 3x^2) + (4x - 12)

We can factor out a common factor of $x^2$ from the first two terms and a common factor of 4 from the last two terms.

f(x) = x^2(x + 3) + 4(x - 3)

Now, we can see that the equation can be factored as:

f(x) = (x + 3)(x^2 + 4)

Step 2: Rewrite the Equation in the Non-Standard Form

Now that we have factored the equation, we can rewrite it in the non-standard form. We want to rewrite the equation in the form $x = \sqrt{\left(\frac{a(b-x)}{3+x}\right)}$ where $x \neq -3$.

To do this, we can start by isolating the term $x^2 + 4$.

(x + 3)(x^2 + 4) = 0

We can divide both sides of the equation by $(x + 3)$ to get:

x^2 + 4 = 0

Now, we can subtract 4 from both sides of the equation to get:

x^2 = -4

We can take the square root of both sides of the equation to get:

x = \pm \sqrt{-4}

We can simplify the expression by multiplying the square root by the square root of $-1$.

x = \pm 2i

However, we want to rewrite the equation in the form $x = \sqrt{\left(\frac{a(b-x)}{3+x}\right)}$ where $x \neq -3$. To do this, we can start by isolating the term $x$.

x^2 + 4 = 0

We can subtract 4 from both sides of the equation to get:

x^2 = -4

We can take the square root of both sides of the equation to get:

x = \pm \sqrt{-4}

We can simplify the expression by multiplying the square root by the square root of $-1$.
