Question

First factor the trinomial as a binomial square and then use the square root method to solve. x2 - 20x + 100 = 36

Answer 1

Factor the trinomial. It is a perfect square.\[(x-10)^{2}=36\]Then take the square root of both sides. \[x-10=\pm6\]Then add ten to both sides and you'll get the two solutions for this problem.
