# How do you solve graphing quadratic functions by factoring x^2 + 6x + 8?

Jun 26, 2018

This factors to $\left(x + 2\right) \left(x + 4\right)$

The y intercept is (0,8)

It crosses the x axis at (-2,0) and (-4,0)

It is a $\cup$ shaped parabola and it has a line of symmetry at

$\frac{- b}{2 a} = - \frac{6}{2} = - 3$

The minimum is (-3,-1)
