What is the expression in factored form?
x^2 + 13x + 42
(x+6)(x+7) = factored form
You can see that it is \((x+6)(x+7)\)
or
Quadratic Formula
\(\frac{-13\pm \sqrt{13^2-4\times 42}}{2}=\frac{-13+1}{2}=-6, \frac{-13-1}{2}=-7\) so it's \((x+6)(x+7)\)
(wow, for me, that was a lot of complicated LaTeX!)
You are very welcome!
