Solve 0=4x^2+12x+9 using the quadratic formula.
MAXImum [283]
The quadratic formula is x =  \frac{-b \pm \sqrt{b^2 - 4ac} }{2a}.  With the values from this equation plugged in, it looks like this:

x = \frac{-12 \pm \sqrt{12^2 - 4(4)(9)} }{2(4)} \\  \\ x = \frac{-12 \pm \sqrt{144 - 144} }{8}  \\  \\ x =  \frac{-12}{8}  \\  \\ x = - \frac{3}{2}

The solution is x = - 3/2
