What is a perfect square trinomial?

Back

A perfect square trinomial is a quadratic expression that can be expressed as the square of a binomial, typically in the form (a + b)² = a² + 2ab + b².

What is the formula for factoring a perfect square trinomial?

Back

The formula is (a + b)² = a² + 2ab + b² or (a - b)² = a² - 2ab + b².

How do you determine if a trinomial is a perfect square?

Back

Check if the first and last terms are perfect squares and if the middle term is twice the product of the square roots of the first and last terms.
