Identify Coefficients: Identify the coefficients of the quadratic expression.The quadratic expression is 4w2+20w+25. Here, the coefficient of w2(a) is 4, the coefficient of w(b) is 20, and the constant term (c) is 25.
Check Perfect Square: Determine if the quadratic is a perfect square trinomial.A perfect square trinomial is of the form (aw+b)2=a2w2+2abw+b2. We need to check if 4w2+20w+25 fits this pattern.
Find Square Roots: Find the square root of the first and last terms.The square root of 4w2 is 2w, and the square root of 25 is 5. We will check if the middle term, 20w, is equal to 2 times the product of 2w and 5.
Verify Middle Term: Verify the middle term.Calculate 2×(2w)×5 to see if it equals the middle term, 20w.2×2w×5=4w×5=20wSince the middle term of the quadratic expression is indeed 20w, the expression is a perfect square trinomial.
Write Factored Form: Write the factored form of the quadratic expression.Since the quadratic is a perfect square trinomial, it can be factored as (2w+5)2.
