Check Perfect Square Trinomial: Determine if the quadratic expression is a perfect square trinomial.A perfect square trinomial is in the form (ax)2+2abx+b2, which factors to (ax+b)2.Check if 16x2+40x+25 fits this pattern.16x2 is a perfect square, as 16x2=(4x)2.25 is a perfect square, as 25=52.The middle term, 40x, is twice the product of the square roots of the first and last terms, as 2×4x×5=40x.Since all conditions are met, the expression is a perfect square trinomial.
Factor Trinomial: Factor the perfect square trinomial.Since we have established that the expression is a perfect square trinomial, we can factor it as (ax+b)2.From Step 1, we know that a=4x and b=5.Therefore, the factored form is (4x+5)2.
