Full solution

Q. Factor.\newline4w2+20w+254w^2 + 20w + 25
  1. Identify Coefficients: Identify the coefficients of the quadratic expression.\newlineThe quadratic expression is 4w2+20w+254w^2 + 20w + 25. Here, the coefficient of w2w^2 (a)(a) is 44, the coefficient of ww (b)(b) is 2020, and the constant term (c)(c) is 2525.
  2. Check Perfect Square: Determine if the quadratic is a perfect square trinomial.\newlineA perfect square trinomial is of the form (aw+b)2=a2w2+2abw+b2(aw + b)^2 = a^2w^2 + 2abw + b^2. We need to check if 4w2+20w+254w^2 + 20w + 25 fits this pattern.
  3. Find Square Roots: Find the square root of the first and last terms.\newlineThe square root of 4w24w^2 is 2w2w, and the square root of 2525 is 55. We will check if the middle term, 20w20w, is equal to 22 times the product of 2w2w and 55.
  4. Verify Middle Term: Verify the middle term.\newlineCalculate 2×(2w)×52 \times (2w) \times 5 to see if it equals the middle term, 20w20w.\newline2×2w×5=4w×5=20w2 \times 2w \times 5 = 4w \times 5 = 20w\newlineSince the middle term of the quadratic expression is indeed 20w20w, the expression is a perfect square trinomial.
  5. Write Factored Form: Write the factored form of the quadratic expression.\newlineSince the quadratic is a perfect square trinomial, it can be factored as (2w+5)2(2w + 5)^2.
