Factor. 25q^2 + 40q + 16 ______

Identify Perfect Square Trinomial: Determine if the quadratic expression can be factored using the perfect square trinomial formula. A perfect square trinomial is in the form of (a^2 + 2ab + b^2) which factors to (a + b)^2. We can check if 25q^2 + 40q + 16 is a perfect square trinomial by identifying a^2, 2ab, and b^2 in the expression. 25q^2 is a perfect square since (5q)^2 = 25q^2. 16 is a perfect square since 4^2 = 16. The middle term, 40q, should be equal to 2ab. Since a = 5q and b = 4, we have 2ab = 2 * 5q * 4 = 40q. Since all conditions for a perfect square trinomial are met, we can conclude that 25q^2 + 40q + 16 is a perfect square trinomial.Check for Perfect Square Trinomial: Factor the perfect square trinomial using the formula (a + b)^2 = a^2 + 2ab + b^2. We have identified a = 5q and b = 4 in the previous step. Therefore, the factored form of 25q^2 + 40q + 16 is (5q + 4)^2.
