Simplify This Expression 4p 9 7p 2

Simplify this expression: 4p^9 + 7p^2

This expression appears complicated at first glance, but with the right approach, we can simplify it effortlessly.

Step-by-step simplification:

  • Factor out p^2: We can write 4p^9 as 4p^2 * p^7 and 7p^2 as 7 * p^2. So, our expression becomes: 4p^2(p^7 + 1)

  • Apply the sum of cubes factor formula: The expression inside the parentheses is a sum of cubes, which can be factored as: p^7 + 1 = (p^3)^3 + (1)^3 = (p^3 + 1)(p^6 – p^3 + 1)

Our simplified expression now becomes:

4p^2(p^3 + 1)(p^6 – p^3 + 1)

This form is much easier to work with and can be used for further calculations or analysis.

Understanding the Concept of Simplifying Expressions

In algebra, simplifying expressions involves combining like terms and eliminating unnecessary symbols or operations to obtain a more concise and manageable form.

Step-by-Step Simplification Process for 4p³ + 9p + 7p²

Step 1: Group Like Terms

The first step is to group terms that contain the same variable raised to the same power. In this case, we have:

  • p³ terms: 4p³
  • p² terms: 7p²
  • p terms: 9p

Step 2: Combine Coefficients

Next, we combine the coefficients of like terms. For instance, the coefficients of the p³ terms are 4, so we simply add them together:

  • p³ terms: 4p³ + 0p³ = 4p³

Similarly, we combine the coefficients of the p² terms:

  • p² terms: 0p² + 7p² = 7p²

And the coefficients of the p terms:

  • p terms: 0p + 9p = 9p

Step 3: Write the Simplified Expression

Finally, we write the simplified expression by combining the like terms:

  • 4p³ + 9p + 7p² = 4p³ + 7p² + 9p
