    Study Notes

    Finding Factors

    • Factors are numbers or algebraic expressions that divide another number or expression evenly (with no remainder).
    • Examples of factors of 4 include 1, 2, and 4.
    • Examples of factors of 2x² include 1, 2, x, x², 2x, 2x².

    Factoring Polynomials

    • Factoring polynomials involves rewriting the polynomial as a product of polynomial factors.
    • This is analogous to finding the length and width of a rectangle, given its area, where the area represents the polynomial.

    Area of a Rectangle

    • The area of a rectangle is calculated as the product of its length and width (A = L * W).
    • The area can be represented as a polynomial expression.
    • The area is related to the length and width by factoring: the area can be factored into its length and width.
    • The width of the rectangle can be considered a factor of the area.
