Factoring Polynomials - Perfect Square Trinomials by Math Teacher Gon
MATH TEACHER GON・2 minutes read
Perfect square trinomials are expressed as the square of a binomial, factored by squaring the first term, copying the sign, multiplying the two terms, and squaring the last term. Examples include x squared plus 6x plus 9 factoring to (x + 3) squared, and 4x squared plus 12x plus 9 factoring to (2x + 3) squared.
Insights
- Perfect square trinomials can be factored by recognizing the pattern of squaring the first and last terms, copying the sign, and multiplying the two terms in the middle.
- Understanding the process of factoring perfect square trinomials, such as (x + 3) squared or (2x + 3) squared, involves a systematic approach that simplifies complex expressions into manageable forms.
