Question 1025972

Describe three different ways to solve x^2 - 2x - 15 = 0. Which method do you prefer and why? Thanks!
<pre>Of the 3 methods, I prefer FACTORING, in this case, and in may other cases, when the trinomial can be factored with INTEGERS.
{{{x^2 - 2x - 15 = 0}}}
(x - 5)(x + 3) -------- Factoring the trinomial
{{{highlight_green(matrix(1,3, x = 5, and, x = - 3 ))}}}
