Summary of WRITING POLYNOMIAL FUNCTION IN STANDARD FORM AND IN FACTORED FORM || GRADE 10 MATHEMATICS Q2

Main Ideas and Concepts

Standard Form of Polynomials
- A polynomial is in standard form when its terms are arranged in decreasing order of the exponent of x.
- Example: For the polynomial p(x) = 2x^3 + 5x^2 + 7x - 5, it is already in standard form.
- The highest degree term should be first, followed by terms of lower degrees.
Factoring Polynomials
- Factoring involves rewriting a polynomial as a product of polynomials of smaller degrees.
- Key concepts in factoring include:
  - Factoring out the Greatest Common Factor (GCF)
  - Difference of Two Squares
  - Sum and Difference of Two Cubes
  - Perfect Square Trinomials
  - General Trinomials
Examples of Writing in Standard Form
The video provides examples of rearranging polynomials into standard form, emphasizing the importance of ordering by descending powers of x.
Examples of Factoring
- Difference of Two Squares: 4x^2 - 81 = (2x + 9)(2x - 9)
- Sum of Two Cubes: Factoring using the formula for cubes.
- Perfect Square Trinomials: Recognizing patterns to factor trinomials that are perfect squares.

Writing Polynomials in Standard Form
- Identify the highest degree term.
- Arrange all terms in order from highest to lowest degree.
Factoring Polynomials
- Determine if the polynomial can be factored using special products.
- Apply the appropriate factoring technique based on the polynomial type:
  - GCF: Factor out the Greatest Common Factor first.
  - Difference of Two Squares: Use the formula a^2 - b^2 = (a + b)(a - b).
  - Sum/Difference of Two Cubes: Use the formulas for factoring cubes.
  - Perfect Square Trinomials: Identify patterns and apply the square formula.
