Understanding the Equation
Before we dive into the solution, let's take a closer look at the equation:
−5−x2−3x3+10x^4
This is a fourth-degree polynomial equation, meaning it has a degree of 4. The equation is written in the standard form, with the terms arranged in descending order of powers.
Step 1: Factor Out the Greatest Common Factor (GCF)
The first step in solving this equation is to factor out the greatest common factor (GCF). In this case, the GCF is 1, since there is no common factor that can be factored out.
Step 2: Factor the Quadratic Expression
The next step is to factor the quadratic expression −x^2. We can factor this expression as:
−x^2 = -(x^2)
Step 3: Factor the Cubic Expression
Now, let's focus on the cubic expression −3x^3. We can factor this expression as:
−3x^3 = -3x^3
Step 4: Factor the Quartic Expression
Finally, let's look at the quartic expression 10x^4. We can factor this expression as:
10x^4 = 10x^4
Step 5: Combine the Factored Expressions
Now that we have factored each expression, we can combine them to get the final factored form of the equation:
−5−x2−3x3+10x^4 = -(x^2) - 3x^3 + 10x^4
Step 6: Simplify the Equation
The final step is to simplify the equation by combining like terms. In this case, there are no like terms to combine, so the equation remains the same:
−5−x2−3x3+10x^4 = -(x^2) - 3x^3 + 10x^4
