Identify the perfect square trinomial: $$25y^2 - 20y + 4$$ , $$25y^2 - 10y + 4$$ , $$25y^2 - 12y + 4$$ , $$2x^2 + 20x + 5$$

$$25y^2 - 20y + 4$$ is a perfect square trinomial because it can be factored as (5y - 2)².

What is the relationship between the coefficients of a perfect square trinomial?

In a perfect square trinomial of the form a² + 2ab + b², the coefficient of the linear term (2ab) is twice the product of the coefficients of the squared terms.

Identify the perfect square trinomial: $$x^2 + 10x + 25$$ , $$x^2 + 14x + 49$$ , $$x^2 + 15x + 36$$ , $$x^2 + 8x + 16$$

$$x^2 + 10x + 25$$ is a perfect square trinomial because it can be factored as (x + 5)².

Identify the perfect square trinomial: $$x^2 + 4x + 4$$ , $$x^2 + 6x + 9$$ , $$x^2 + 8x + 16$$ , $$x^2 + 10x + 25$$

$$x^2 + 4x + 4$$ is a perfect square trinomial because it can be factored as (x + 2)².

What is the significance of recognizing perfect square trinomials in algebra?

Recognizing perfect square trinomials helps in simplifying expressions, solving equations, and factoring polynomials efficiently.

Identify the perfect square trinomial: $$x^2 + 18x + 81$$ , $$x^2 + 20x + 100$$ , $$x^2 + 12x + 36$$ , $$x^2 + 14x + 49$$

$$x^2 + 18x + 81$$ is a perfect square trinomial because it can be factored as (x + 9)².

What is the formula to factor a perfect square trinomial?

The formula to factor a perfect square trinomial a² + 2ab + b² is (a + b)².

Identify the perfect square trinomial: $$x^2 + 2x + 1$$ , $$x^2 + 3x + 2$$ , $$x^2 + 5x + 6$$ , $$x^2 + 4x + 4$$

$$x^2 + 4x + 4$$ is a perfect square trinomial because it can be factored as (x + 2)².
